Well, I just wanted to ask if anyone who is using the old MAF-T is using the GM MAF in blow-through mode or any other way. The reason I ask is my A/F ratios get pretty crazy at initial start-up, such as off the charts lean. Then after the car warms up a bit they go pretty rich at idle, 12's. Then I'll drive it around and I can't get under any type of acceleration till the car fully warms up, even then I have to re-start my car to accelerate at all. After the re-start I can boost away but the A/F ratios go extremely rich at idle 10.0. And 12.2-13.4 cruising. Im running about 40psi fuel pressure off vac, my tps sensor is unplugged right now because my countless attempts at calibrating it only lead to failures. So im expecting to be running richer with the tps being unplugged, but the start-up A/F issues seem odd. Maybe a bad CSI time switch? I plan on going MAF-T Pro soon, but I don't have the funds and would like to find out why my A/F issus are so wacky... Any ideas? And could running my MAF in induction mode (on the intake pipe) change anything? Thanks all!
