Porsche Cayman GT4 Tuning with Acceleration Videos

The Porsche 981 Cayman GT4 is a animal that only gets better with performance parts and a ECU Tune.  VR Tuned is able to flash the new SDI9 Cayman GT4 3.8L via the OBDII port to allow customers worldwide to take advantage of our tuning.  The 981 GT4 receives a custom tune that provides the car with faster throttle response, more low end torque, and harder pull through the revs.  This is not a “off the shelf” map from a handheld but a unique calibration for your vehicle.  Utilizing the DimSport handheld unit, we take a matching software ID to custom tune your car to the modifications you have.  With gains of 20 horsepower, the overall driving performance you feel on the road and the track cannot be replicated from a basic dyno run.  If you are looking to truly enhance your Porsche 981 Cayman GT4, then a ECU flash is definitely recommended.

Our customer had his reflashed as pictured below.  When writing the large file, it is always recommended to use a battery charger or tender.  After flashed, he immediately took it out and show some acceleration videos.  His reviews on the Cayman forums and Facebook groups give a perfect first hand representation of the performance increase.  If you are interested in ordering this ECU flash, view the Porsche 981 Tuning Here.

Lord Disick Mercedes AMG GTS Build at Vivid

The Mercedes AMG GT-S coupe is a pretty awesome car.  For the longest time I was more of a BMW fan than Mercedes.  When we got our Project C63 my eyes were awoken to what Mercedes did.  The CLS63 we built was fun but a little to cush.  Our CLA45 is a reminder of the days driving the Mitsubishi EVO and Subaru STI.  But this AMG GT-S is right up Porsche ally and its a monster!  This car is a little special because of the owner.  Personally, it does not matter if you are a celebrity, sports star, or joe schmoe.  What is important is that you are down with cars and get it.  Car guys are car guys.  Scott Disick is a true car guy on the higher end of the car scale.  Having owned cars like the Ferrari 458, Mercedes SLR, Lamborghini Aventador, and even Bugatti Veyron, he is in touch with speed.  Over the years we have talked about different vehicles and finally we got together to make his new AMG GT-S boosted up.

The AMG GT-S was picked up and delivered to our shop in Gilbert, Arizona by our friends at Desert Eagle Auto Transport.  The car had just 3000 miles on the clock and our plan was to give it some more power with Agency Power and VR Tuned.  We wanted to show our capabilities against some of the other well respected Mercedes tuners.  In addition to the performance, we discussed giving the car a new exterior look inspired by some random google searches.  Where the Prior Design Widebody would be awesome, we went a little subtle with a wrap and wheel coating.  The first thing we did was a baseline test to see where the car was at.  We ran the car on our Mustang All Wheel Drive Dyno with 91 octane fuel and outside temperature around 50-60F.  Our baseline test yielded 416 awhp and 430 ft/lbs of torque.  Even though the car was rear wheel drive and we ran it in awd to avoid crazy dash lights with dyno mode, it had trouble keeping traction in 3 gear pulls.

Our first step in this build was to do downpipes.  The new 4.0L V8 engine is very strong and what we have seen from the past with our CLS63 and other turbo cars is that the downpipes give the most performance.  We chose to do catless downpipes which gave the twin turbo M178 engine no restriction and even faster turbo spool then what Mercedes designed with the “hot inside V” configuration”.  Turbocharged engines really don’t need backpressure, however if no restriction, the cars can get very loud.  So our fabrication team with Agency Power begin the develop of building the downpipes off the car and then jigging them up.  Now another part we decided to do for fun would be a straight pipe race exhaust.  Newer cars such as the Mercedes GT-S have a good flowing valved exhaust to be comfortable at cruising speeds yet aggressive when in race mode.  With a straight pipe system, this would be geared towards the track guy or those with #nocare!  It does save a ton of weight off the back end since there is no muffler.  While the downpipes were under way, we also began building this exhaust system to later jig up as well.

With the exhaust system underway, we did some testing of our VR Tuned ECU Flash for the Mercedes GT-S on our dyno.  Typical gains are rated for higher octane such as 93oct or up.  But in Arizona and California we have 91oct so the performance is slightly less.  With a drivetrain loss of 20-25%, we usually guess at around 22% from stock.  However the estimation is not always spot on so we look for what are the gains from our baseline to tuned.  The ECU flash allows us to adjust boost, fuel, and timing, as well as other parameters including that for catless downpipes.  Stock power is rated at 503 HP with 479 lb-ft(600 N-m), where once tuned goes to 615 HP | 585 lb-ft(664 N-m).  Thats a very strong gain and grows even more with the exhaust components.

With the package all put together, we did a final dyno and tests on the car.  The first impression is the insane sound that now comes from the 4.0L V8.  The straight exhaust is intense and makes the Mercedes sound like a mean GT3 race car.  When on the dyno the torque difference is menacing and makes the turbos come on extremely quick.  Our baseline run had the peak torque at 3300rpm making 430ft/lbs where now 3300rpm makes 510ft/lbs and peak torque goes to 526ft/lbs at 3700rpm.  3700rpm has a gain of 100 ft/lbs of torque over stock!  This gain in torque continues which tapers down to redline while still making 60ft/lbs of torque even at 5000rpm.  6100rpm is making around 50ft/lbs.  Horsepower is a very linear increase starting at 3300rpm with 40awhp and climbing up to a peak of 70awhp over stock.  This is about a 90bhp gain on 91octane which is very good.

Thanks to our friends at EAWraps in Scottsdale for this full satin charcoal wrap they did.  Having had cars wrapped by other companies in the past, this is one of the best jobs I have ever seen.  Its flawless and goes great.  Even down to the emblems and center caps were touched.  We also added a little flavor by powdercoating the stock wheels a bronze color to pop out.  Check out the videos and pictures below and let us know what you think!

Porsche 991 Turbo S Power Package of Amazing

We have been on a recent rampage of Porsche 991 Turbo projects and this Porsche 991 Turbo S Cab is no different.  This customer fell in love with our Project 991 Turbo that we did and wanted the same look and performance.  Being his 2nd Porsche 991 Turbo with his first as a coupe, the cab with sexy red interior is going to turn out pretty awesome.  The first round of mods is all about performance here.  With a quick installation of the H&R Springs to give the car a nice stance once done, the rest will soon be added. Round 2 will come soon with Niche 2 piece Misano candy red 21 inch wheels, a Vorsteiner front and rear bumper, and a fresh matte or gloss white wrap from EAWraps.  But first, lemme make some boost!

So our formula for these cars has been the same.  VR Tuned Tuning Box Kit, Agency Power Titanium Exhaust, Agency Power Y-Pipe, Agency Power Intakes.  The Tuning Box Kit is a plug and play device that works with the cars boost, manifold, and cam sensors to change the mapping of the vehicle giving it huge gains in torque and horsepower.  Our Agency Power titanium exhaust original design has a beautiful tone while keeping the stock catalytic converters for emissions purposes.  A new feature on this car is the brand new Agency Power quad titanium tips.  The burnt blue tips are a perfect replacement to those rectangle jobbies and feature a nicely etched AP logo.  Our Y-Pipe helps improve the air flow from the intercoolers to the throttle body with larger diameter piping and a better merge collector.  Finally is the AP intakes giving more forced air with the high flow cylindrical cone filters that fit right under the air ducts for the rear decklid.

We have done 2 articles now comparing the modifications of the 991 Turbo and Turbo S with parts from Cobb Tuning, GIAC, Akrapovic, Sharkwerks, and Agency Power.  Our most indepth article showed the difference in how the Cobb Tuning compared to the GIAC flash, but then compared to our VR Tuned Tuning Box Kit here.  We then revalidated our findings with this other Porsche 991 Turbo S that we showcased about a week ago here.  This showed the consistency of the basic bolt-ons and tuning which included the Cobb AccessPort, Akrapovic exhaust, and BMC air filter.  So now how does this other Turbo S stack up with the VR Tuned Tuning Box.  Tests are always completed on our Mustang AWD Dyno using 91 octane here in Arizona.  Typical drivetrain loss is 20-25% and tests are usually run in 3rd gear.

Our completely stock 991 Turbo S baselined with 444 awhp and 431 ft/lbs of torque.  With all the parts installed and ran again under the same conditions, the peak numbers were 468 awhp and 545 ft/lbs.  No the car did not only make 24 horsepower.  There might be some differences in tests with fans on the intercoolers or radiators, but its a small negligable difference.  It had massive gains with 75 awhp at 3700 rpm that climbed to about 90 awhp at 4280 rpm and then back to 75 awhp at around 4700 rpm.  The car continued with 50 awhp gain around 5100 rpm and slowly tapered off from 40 to 30 to 20 horsepower.  What is truly impressive is the torque.  With the new Y-Pipe and intakes, the throttle is much quicker and the turbos spool faster.  Right away at 3000 rpm we are making 50 ft/lbs more torque and it shoots up massively to a gain of about 120 ft/lbs at around 4000 rpm.  Much like the horsepower, it starts to fade off up top where it crosses paths at 5300 rpm while still gaining about 50 ft/lbs.  I would say the tapering is interesting, but is it?  Lets look at the other cars (graph) below.

Whether the Turbo or the Turbo S, the end gains are going to be the same as the turbochargers are the same but the Turbo S has a slightly more aggressive map stock.  So our previous 4 cars tested including 2 Cobb Accessports, 1 GIAC tune, and 1 VR Tuned Tuning Box were similar.
