Xact Dyno, Tempe AZ

Tim did an awsome job my car made awsome power for only being on 91 pump gas i highly recommended going to tim hes patient and takes his time to get the most power out of your car.thanks Tim I will be sending my customers to you for dyno tunes.thanks agian buddy

Great guy, great tuner, great prices. Never had a problem with the cars i take here and its been a lot.

Tim does an excellent job, great communication and answered all my questions. Recommended!

Tim @ xact dyno was amazing, he spend several hours diagnosing the problem on my supra and didn't even charge me. This guy & his company are top notch for tuning & his prices are super reasonable as well. If you are looking for a straight shooter & a badass tuner look no further.

Tim's done a lot of work for us, great person and fun to work with! Super knowledgeable!

Tim is a super cool dude. Isn’t overpriced and treats you right. Highly recommend. Have had several vehicles tuned by him that last!

Best tuner out there he knows what he’s doing.took my 98 Civic with a built gsr swap in for a tune it did not run before I took it to him got it back ripping around strong.
Any time I have questions with anything on my engine or tune ect he’s very responsive and quick to help out. He uses quality hub dyno as well -this is not a backyard tuner —I highly recommend Tim xact dyno

Hands down Tim really did a great job on my vehicle. Was hard to find someone I could trust my vehicle with and after my experience with him would be the only person tuning my vehicle. Knowledgeable and definitely wont disappoint.
