Hi all,
Long time lurker. Tried to tune my stock 2011 truck 6L80 with "The Tuning School" transmission guide. It woke the truck up, but the shifts are not the best and has some random flare-ups. WOT shifts are bad and feel like I am doing a neutral drop on the trans which I really do not like. I am done trying to play with the trans tune and am wondering who are the best 6L80 tuners out there I can pay to tune my trans via email?
Or if anyone knows a reputable tuner in the South Houston area?
Thanks for any help.
Ben
