If I sold you a partial tune due to a part or mechanical issue, the completion is still available. I had a replacement MPVI-II sent to me, I just never started tuning commercially again due to the persistent equipment failures I had experienced.

I have never met a more dedicated tuner, and I would love to. So I can pick their brain!

I was born with the math, I learned to love the V8. (And my V-Twin when it's actually running)

Currently closed for business until I figure out how to replace my MPVI2 and retain my licensing for all of my customers. (Board is fried due to a ground loop on a customers harness)

This is what I have come to expect from any and all of the "reputable" tuning shops local to East Texas.

Guy did maybe one update to the MAF curve and absolutely 0 smoothing, LS swap cranks up and sits at 3000 rpm for a few seconds. Flat WOT 28* of spark timing from 3,000RPM+. This is all what they would like you to believe is a completed tune.

I'm tired of seeing it, if they can't be trusted with a brick and mortar shop, it hurts the entire industry.

Sometimes you get caught up with whether or not you can, and forget to think about whether you should. 😂
