I'm questioning the tune on my '03 Mach 1 w/ Procharger. It was tuned by Craven Performance before I bought it. It's ALWAYS reading 14.7:1 AFR until I'm practically at full WOT, where it finally goes to 11:1. Engine load doesn't seem to matter at all, it's 14.7:1 at all time unless flooring it. This doesn't seem safe to me, can an expert chime in?
I'm taking it to Bobcat either way. I'm waiting for a call back from his shop to schedule a tuning. Just wondering if I should really even be driving it like this, or just be really careful about engine load and take it real easy.
