Awesome customer service and great improvement on the car. Definitely tell a difference within each tune. Very helpful and will walk you through each step. I didn’t know anything about computers or how to tune or the basic. Scott was able to help me through it all and understand it all.

These guys are the absolute best in the industry hands down! If you need something for your V look no further, no one has more knowledge and experience. From filters to tunes, these guys have the data to back up their claims. Been a customer and will remain as long as I own anything they sell parts for. Last order took 2 days from order to my door… that is fast and was standard shipping…

I wanted to give an update on my Tapout Tuning adventures on my 2017 ATS-V after getting the purple belt installed by Tapout Tuning back in 2021.  My CPO warranty was almost up at 50,000 miles, so I figured it was the perfect time for an upgrade.  Now, with a whopping 89,000 miles on the car (and an impressive 39,000 of those with the purple belt and kill tune engaged), this car is still running like an absolute beast!  We went from a respectable 464 HP (at the crankshaft) to a mind-blowing 615 HP (at the wheels)!

This is a true testament to the quality and durability of Tapout’s work.  I don’t do 1/4 mile pulls often, but I do enjoy the weekend street racing, and this car has held up beautifully through it all.  I’m religious about regular maintenance (oil changes before 50% life left, Brisk plugs every 5k miles, transmission flushes, etc.), but the purple belt has definitely made a noticeable difference in both performance and longevity.

I can’t say enough good things about the Tapout team.  Their customer support is top-notch, and they’re always quick to respond to any questions.  Jorge, you’re a wizard with the LF4!  I’m even taking another trip to Gatlinburg in September (my 9th since the purple belt install), and I have zero worries about my car’s performance.  If you’re looking for reliable performance upgrades that will truly last, and a company that stands behind their work, look no further than Tapout Tuning. if you have any questions and are considering Tapout feel free to reach out to me with questions at Mlsharp301@hotmail.com.

Scott has been my tuner (I believe I was his very first or maybe second customer) since May of 2018 after he had spent 10 years of setting drag racing records tuning and driving Pontiacs along w/ his brother Bob. He told me he needed a new challenge. Having tried other tuners the first 6 months I owned my 2016 ATS-V (w/ crappy results we won’t go into) I contacted Scott Cook at Tapout Tuning and asked him to tune my LF4 and have never regretted that decision or looked back. My ATS-V has been my daily driver since day one and now has 201,688 miles of Tapout tuned miles on the clock. Previous testing at Tapout HQ in November of 2022 showed my OEM valve springs had become worn out and I was losing HP after about 5500 RPM. Scott suggested a new set of Tapout Valve Springs along w/ a set of performance cams I had Jorge slip in during the operation. I was making a trip from my home in Florida to Ohio anyway and Scott squeezed me into his schedule during the last week of May 2024. Tapout is fortunate to employ Jorge Munoz who is recognized in our community as the THE top LF4 mechanic. ( I moved from Ohio to Florida w/ plans to use Jorge as my LF4 go-to tech and Jorge promptly moved to Ohio….go figure). After a two day stay at Tapout HQ Scott and Jorge had my car strapped on the Dynojet and after about 5 or 6 WOT pulls Scott had recovered the 50 HP I had lost due to the worn out valve springs but added an additional 50 or so after 5500 RPM. My car is a beast once again and I couldn’t be happier w/ the results. In case you missed it my car has 201,688 miles on it and has posted a 10.505 at 134 mph in 2023 at the Cadillac Attack Event at that time I had 186,000 on the clock. That in its self has to be a World Record. I hopefully will head to the track tomorrow w/ a plan to set a personal best 1320 of 10.25@137. Make sure to give my friend Scott a call when you feel the need for speed.

I am absolutely amazed with the quick response and quality of tapout tuning. Coming from several platforms and finally to a ct5v bw and ct4v bw i can officially say you guys have the greatest service I’ve ever seen. I spoke to Scott on a weekend and got parts which weren’t even your mistake sent to make up for it. (Note: I did end up contacting Green Filters and they sent me a replacement filter and kit free and overnighted it as well. All i really cared for was the blackwing sticker to shove on my laptop next to the tapout tuning sticker.) Absolutely the best quality and response I’ve seen especially since i didn’t notice Scotts email until i got home and saw the package.
