Got tired of chasing lean codes for the last 3 weeks & finding no vacuum leaks. Fuel pressure is good, & fuel trims look good. Everything on the scanner looks good. Decided to take the car to the dyno yesterday. Lo & behold, it actually IS running lean, between 15:1 & 16:1. I got my chip from SCP last year. I'm not sure what A/F ratio Bill has them set the chips up for, but it was before the mods I did this past winter, magnaporting the blower, adding a double IC, & porting my exhaust manifolds. Not sure of those mods would make the car run leaner, but it seems feasible. Anyway, time for a custom tune. In the meantime I just have to keep my foot out of it.
