just a few q's
so i finally finished my TPI build, she's got a 305 running a .451 lift cam, nothing outrageous. I hooked up my Snap on MT2500 to it and pulled some data from her, I've got a tps voltage of .58v @ idle (ill adjust this back down) but here's what trips me out, is when i'm driving my A/F guage will drop from stoich to totally lean with the shifts of the tranny, I dont hear any pinging or anything like that, and it seems pretty damn powerful and I have a BLM of 115. anyone see any issues here? again im new to this aspect of things.
