FYI, the metro doesn't have a scangauge anymore. So, desperate for feedback, I threw in a vacuum gauge I had laying around. Anyone know at what psi enrichment kicks in here?
I had a little test drive, it's kinda cool actually, real responsive. Better than tps alone (where is my foot again?). I feel pretty confident that the training with the scangauge improves my odds though. It may be that the cheapest might be to borrow a scangauge and then install a vacuum gauge. Maybe your library would buy a scangauge?
