Hi everyone,

Have a GXP 2007 have had mods, exhaust, cold air intake, intercooler, GMPP stage II. Great performance most times, get engine light sometimes. Saw a local, trusted mech. read codes gave me a printout, said I need to see someone that can tweak the after OEM components to work together. I have read many threads answered by others that think newbies are a pain, well here is another one... So who is recommended in mid Michigan to talk with?

Thanks, Tollman
