Hi all - just picked up a 16 with an Alpha turbo already installed. I've noticed a coupe of times that if I wind it out in 2nd and then hit 3rd too quickly, the engine will stumble as if it's hitting a super lean AFR. I'm absolutely terrified to run it hard at all at this point. It doesn't have gauges installed and I'm happy to install, but I'm new to turbos (NOS guy :)) so I'm not entirely sure how to proceed. So a few questions :
1. Is it possible to use ODB to spot lean mixtures?
2. If I do find it to be lean, what'st the next step? on NOS builds I've always upgraded fuel rail and injectors - can I tell if that has been done already?
3. Is there a way for me to be able to determine which EFI MAP is being run?
thanks much!
