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
