I mainly do GM, like you, and on the occasions I have to do a Ford(MAF only garbage) or a Dodge(SD even worse garbage) it's amazing how bad these things are and can still get thru CARB testing when stock or with somebody's(Rousch, SCT, many many others).
I grew up on SD tuning(early 90's), so, it doesn't bother me but MAF is king IMO.
I get a lot of tunes to do that someone else has completely screwed up the driveability. Many have spent a Lot of money and the MAF tune makes all the power, and can't drive at all at part throttle on different days, because they got into the maf tables figuring a percentage here a percentage there works fine. Plenty of times I just look at the MAF table(even on Fords) and just put it back to stock(if it has the range) and start over from stock. Fix the tube, or, stock MAF and go, Yuck.
Anyway, good to have a talk :)
