Best shop to tune my turbo ecotec?

Well since he has one then I’ll just let him use that one when I go. I appreciate the offer though. That was cool.

It can be tuned via hp tuners but it’s a very difficult pcm to tune. Someone already tried and failed. Thats why I am stuck using hahns locked tune since they took 2 years to get it right and they say the fmu is all i need to tune it further. the timing and tq mngt have all been taken care of as well as shift points and pressures. I just need to get the air/fuel ratio to be happy.
