Kyle brought his car in from Indiana after being unsatisfied with two previous tuners.  With the Tapout Purple Belt Performance Package and our custom dyno tune, this car produced a beautiful powerband peaking at 617 whp and 645 wtq on E85.

Tom from New York wasn’t satisfied with his old tuner.  He liked the top end power, but his car ‘made no boost down low and had weak low end power.’  We took care of this for him with our Purple Belt Performance Package and a full E0 to E60 flex fuel tune.  When Tom left our shop his car made 600 or more whp and/or wtq all the way from 4,000 to 6,500 rpm.  Our tunes produce the best powerbands by far, and that’s why people drive in from all over North America every week to convert to Tapout.

Joe lives a few miles from our shop in Ohio, and just purchased his beautiful ATS-V from someone in Texas.  After performing some fuel system upgrades to get him up to our Purple Belt Performance Package level, we did a baseline pump gas run on his previous tune.  The car made respectable peak power of 498 whp and 490 wtq on 93-octane fuel.  With no changes other than our custom tuning, we improved his numbers to 518 whp and 555 wtq.  That’s 20 more whp and 65 more wtq than another well known ATS-V tuner.  And the best was yet to come.  We then added some ethanol and tuned the car on an E50 fuel mix.  Final results were 604 whp and 628 whp, with a much improved powerband.

Rodney drove in from Virginia for our Blue Belt Performance Package.  His baseline numbers were 430 whp and 418 wtq, and he could already beat his friend with a Camaro SS by one car length.  He left our shop with 505 whp and 493 wtq.  With gains of 75 whp and 75 wtq, his Camaro friend no longer has any chance!

We worked with Nick from Georgia to do a remote dyno tune on his ATS-V.  He has intake, spark plugs, Tapout Stage 1 LPFP, fuel cam and exhaust mods and was running E60 fuel.  Car made 629 peak whp and 623 peak wtq SAE.  But that doesn’t tell the whole story.  Some tuners will advertise their ‘600 whp tunes’ when the car barely hits 600 whp for 100 or maybe 200 rpm.  In Nick’s case, his ATS-V produces 600 or more whp and/or wtq all the way from 4,400 to 6,700 rpm, which is basically the entire powerband!  How much fun do you think this car will be?
