tuner in the st paul area?

[mtdave2]

Trying to find a good tuner in the st paul area. id love to find one of the rare guys that can work with the e78 ecm. but, if not someone who can tune the e38 with the 6l90 trans.

i would really rather not pull the valve body out of the trans and send it to someone to tune. local would be much better!

if no one is local, who can do the e78?

BTW i have the odd 2018 L96 6.0 with 6l90 trans

I would ask the same question over on LS1tech.com. If it's a mostly stock combo you could consider a mail order tune. I did that with Frost Tunes on a stock LS1 and it worked great.
There is Schwanke (spelling?) in Springfield MN.
TPIS does tuning but I don't know if the have a chassis dyno. Also there is a Corvette shop kind of west of MPLS that tuned my BMW LS swap. I don't recall the name but they did a great job. They did have a chassis dyno.
Why would you have to pull the valve body to have your combo tuned?
