So i put a new pump in, new MAF, new regulator, and scaled the injectors correctly(i think). Injectors are no longer going over 100%!! YAY!! But, Im either still lean up top, or my autometer wideband is crapping out (it reads 14.7 just fine though cruising) PLease look over the work I have done, and school me if Im still wrong somewhere. Thanks!1765617657

looking at the log, it would appear the o2's are reading rich, when my wideband was telling me it was 15:1!!! Im going to replace the guage tomorrow.

What injectors do you have...?

They are truck flex fuel injectors. I'm going to reduce the maf where I raised it by about 5%. I still have a tbss intake and a dbc 90mm tb to install yet, so a little rich is ok for the time. This has been a real interesting experience. I need to buy my own cable so I can keep fooling around with it and do the wife's suburban.
