Last night I got on her hard, and I think right around the 2-3 shift shiat hit the fan. I got reduced engine power, afr on the wide band pegged lean, service 4 wheel steer message. The truck had no power but i was able to coast the last mile to my house and park it. I haven't looked at it yet today, but I'm gonna go out and try to start it. I don't have efi live yet so I don't know what info I can gather.

Yep, you need EFI live BAD so you can see what's going on. I never knew how important it was to have the software yourself until I got it for myself.

it will probly have a code wich would make this a lot easier. I went into REP on a big boost spike while playing with a boost controller once. Cleared it and it never happended again.

btw. if you shut the truck off for a minute and turn it back on all is normal again.

Truck was fine today. Code was p1516 so could this possible be the boost issues with the tbss 90mm vs the car 90mm? I wish I could log so I knew why I went into this. Happened at the top of second gear.

i had that problem with the tbss throttle body. same code and same condition. only i am n/a. switching the the car style fixed the problem.
