Wow, with all this info, I'm actually getting a good idea of why my car runs strong in some places and not so much in others. I can literally feel when the fuel and timing kicks in, and know it's not something not working right. All the charts coincide with the things I'm noticing about the power band as I feel it on mine. I am also starting to realise that the stock maps definitely leave much to be desired.
A 93 octane map?

Does anyone know the actual difference between the maps for the 88 NA cars and the earlier ones? Are they more agressive? Would a stock 88 chip be an upgrade for a pre 88 car?
