This is a really basic question...I bought my 87 GN last year and have done a lot of mods to it since then. I put a 6266 dbb precision turbo on it, alky control kit, 60 lb injectors, 6.1 TT alocohol chip, powerlogger, walbro 340 with hotwire, AEM wideband and am trying to figure out how to correctly tune the car. I realize I can change the bottom 8 units with the powerlogger and I have read and reread the instructions but don't know what to change based on the data I have logged...Is the object of the tune to keep the blm's at 128? Anybody that can point me in the right direction would be greatly appreciated.
