“Working with Derek was great. He is very communicative if you have questions. The whole process was straightforward and the instructions were very clear. My tune was done in 7 revisions despite careless errors on my end, and the car feels 10x stronger than it ever has before and without sacrificing any daily drivability. If anything the car is smoother and more responsive than it ever has been in normal stop and go in town driving.”
“Working with Derek was simple, professional, and straight forward. I get so much enjoyment when I get that email about a new revision to the map. You really can feel your car changing and evolving with each revision. If you can upload off the shelf tunes then you can record, send datalog info, and upload new maps. Its simple. Highly recommended if you're full bolt on. In particular, if you're experiencing pops and bangs from decelerating (the really loud gun shot kind) means the engine is running too rich. It's getting too much air and not enough fuel. This Custom tune will fix that!”
