| Re: Who can do a tune on an '07 ESV w/a 6.2?
Hi there, I am new to this site but not GM Trucks. If you have not gotten any answers on this look up Blackbear Performance and talk to Justin. He's got great customer service but a 6 week waiting list if you are going the mail route. Worth it in my opinion, I will be getting a live tune from him once our schedules can match. |
