After looking around for more power and some other parts for my Cadillac ATS 2.0T Turbo, I discovered Pfadt Racing, a forum sponsor, and their comprehensive line of aftermarket power adders, their EFR turbo kit, their tuning portfolio, and their comprehensive line of suspension components. I decided to give them a call and then found out that not only do their parts power the fastest ATS in the world, but they also had an install shop that is fairly close to where I am, so after checking out their local install shop, Late Model Racecraft and their dyno facilities, I placed an order for the Pfadt Racing tune for my ATS.
Pfadt Racing is the industry leader in the corvette world for the best parts money can buy. Parts and tech from Pfadt racing power the fastest racers within the corvette racing world, and even GM's own look to the expertise of Pfadt racing for their power and suspension needs. I had previously only have heard of Pfadt's successful motorsport program within the corvette world, but then found out that they have dealers and install facilities located across the united states and other countries that are established corvette and Cadillac CTS-V specialists.
Pfadt Racing is also an independent entity that manufacturers 100 percent of what they sell in the united states. Proudly Made in the USA.
The Pfadt sales rep who answered my call was very professional, courteous, and I felt very comfortable placing an order from them. The Pfadt guy was very knowledgeable about just about everything I could have asked him on my car, and was never pushy and very pleasant altogether to talk to. Pfadt Racing is known in the corvette world as having the best customer service and feedback in the industry.
When asked about the Pfadt tuning program, Pfadt Racing has a very strict and comprehensive quality assurance program that stipulates that each and every part must pass not only dimensional checks but also functionality checks for any deviation in workmanship, material, and even aesthetics, each part must even fall within the smallest fractions of weight deviation in order to pass Pfadt Racing's standards before being shipped to the customer.
Despite having been testing the developed Pfadt Racing tune since January of this year, the Pfadt engineers felt that having tested their tune on no less than a dozen vehicle for a combined total of 200,000 miles were they then able to confidently sign off on releasing their tune, and despite having sold a lot of ATS tunes already, their customers are primarily corvette or cadillac customers that have an ATS as a second car, and usually not as active on the forums.
I am reviewing this ATS tune from Pfadt with Pfadt team confident of their product and without prejudice either towards or against them, and my ATS is my daily driver. The Pfadt sales guy did ask me if I could find a dyno facility of my choice and then post on the forums what I thought of the tune, be it positive or negative.
After seeing one of Pfadt Racing's ATS's claim the title of the world's fastest ATS I was ready to order and after a few days of waiting, UPS dropped off a Pfadt labeled box.
I ended up picking Late Model Racecraft for their dyno facilities, not only because they are an industry leader in very high powered GM car builds, with most of their customers happily driving away with over 1000 horsepower, and even a few dodge vipers with 2800+ horsepower and sub 6 second quarter mile street cars, when I arrived at their shop, they had a line of Lamborghini Gallardo's, Dodge Vipers, CTS-V's, and ZL1 camaro's parked in front of their shop, what a sight!
Jay the operations manager at LMR personally dynoed my car personally.
The Pfadt Racing ATS tune was very easy to install and took no longer than 2 minutes total on a windows computer with a USB port. I would say that loading the tune was very straightforward and easy to use, even for the computer illiterate. The Pfadt Racing tune comes with a loader cable that allows you to return the vehicle to stock at any time.
The car was run on the dyno without cooling off prior and only two runs were made with a total of 2 min between the two runs, the time it took for the tune to install.
The dyno video and dyno graph are attached below.
The dyno at LMR is a dynojet 248 that Late Model Racecraft calibrates every month, and in Houston the weather was a cool 94 F, and the dyno room was not air conditioned, it must have been 105 F + in there when we dynoed the car. No additional airflow was generated over the vehicle, what was in the dyno room was what it got, not even a large fan blowing towards the front of the vehicle, there were no fancy air feed system supplying cold air to the car.
Only two runs were made because dyno runs are expensive and I did not want to pay for a bunch of dyno runs, what is shown is what I documented, stock vs tuned.
My car is completely stock and has an automatic transmission, and therefore dyno numbers are going to be slightly lower than those of cars with manual transmissions.
The Pfadt Racing ATS tune picked up power across the board, and picked up 55+ ft/lbs of torque at the wheels mostly in the area under the curve and gained me 32.21 peak horsepower at the wheels. At around 3750 RPM, the Pfadt Racing ATS tune picked up an astonishing 70+ HP at the wheels vs the car stock. No power was lost in vs stock even at higher RPMs with the Pfadt ATS tune, showing Pfadt's technical superiority vs all the others. I'm sure if the temperature was not as hot or that if the vehicle was allowed to cool between the runs for a longer duration, the tune would have picked up far more power to show for on the dyno sheet.
On the street, the car feels like it is a totally vehicle, where as stock the car would occasionally hesitate and just not feel all that powerful, after the tune my car seriously feels like its a V8; with the Pfadt Racing ATS tune, the car is eager to please and always attentive to any throttle inputs, all the previous hesitation that the stock car felt is gone completely. The transmission shifts very crisp and very fast but never uncomfortable, almost like a dual clutch transmission with the Pfadt tune installed. I am absolutely happy with the results and would gladly recommend this tune to everyone.
Interestingly, the Pfadt ATS tune looks like it runs slightly richer than the stock tune.
