Let me see if I got this straigt, you put a 550s and Z32 burnt chip in your ECU, and with the stock MAF and injectors it's running crappy and your confused by this? Put the Z32 and 550s on there then see how it runs. 11.5:1 is safe, it's not extreme and it's not really conservative. getting into the 12:1 and 12.5:1 area is really starting to create hotter combustion events and on a street tune is definatly not worth it. At least not without a standalone, a wideband, and a very knowledgable watchful eye.
