I met Justin for a live tune in Bentonville yesterday and he worked his magic on my truck. It's still no rocket ship but really came alive and I averaged 21.3 mpg on the way back. I had him raise the shift points a bit, firm them up, remove the AFM and speed limiter and whatever else he does that's over my pay grade LOL.

I just have the tune, CAI, vette servo and muffler for now but I want to go heads/cam, converter, LT's and 4.10's next.

Justin is very professional, great at what he does. Thanks a bunch!

 

had no real issues with his mail tunes till i went cam stall 80e swap then i needed a live tune. i was always getting new tunes and he kept sending them with no issues. good guy to deal with

 

Black Bear gets an A+ in my book.

 

Roger that.

 

Still happy as can be with the tune I got from Justin. Still need to do a data log to send back to him for some tweeking and get my stock tune for if I ever go back to the dealer.
