Max torq settings mycar has a yank3600 installed car ran 13.2/105 before 13.5/98 after I think the tune is right lockup and all still working on the shift points they are a little early but my question is my car seems real flat at the top I noticed on some other hp files that everyone with a stall raised the max torq 639/640 mine is still at 350 it says something about voltage drop to the fuel pump what does that setting exactly do

You want no attempt to limit engine torque on its
own. You probably ought to keep some trans torque
management which only affects things during shifts.
There some attempt to model fuel pressure by the
pump voltage drop, but unless you understand how
that all works and what the voltage drop really is,
I wouldn't screw with it. Certainly not before putting
a pressure gauge to the Schrader and seeing what
you're getting there, at the big end. A significant
drop from idle-range readings would indicate a need
to mess with that stuff somehow (but begin with a
fuel filter change-out).

yea did some logs yesterday and in the 3000/4000 range I was getting +10/+12 unhooked the maf ran it in SD everything uunder 4000 was + or -2 of zero and my commanded 11.7/1.250 was dead on at WOT with the maf hooked up it was like 13.8/14. could this be a dirty maf that just happened to go bad the same time as the install and already changed the filter any more advice would be appreciated. just starting to understand logging the VE table pretty well I think but not quite sure how to log the maf

People do misguided things like using oiled type air
filters. A careful hose-down of the MAF with a good
cleaner is a good idea. QD electrical contact cleaner
or auto parts store MAF cleaner. Nothing that
"lubricates", if you're shopping "contact cleaners".

when going to clean maf noticed the corrugated hose was not connected to the TB very well came off w/o any tools wondering if it could of been drawing air between maf and TB that would cause a lean condition right, may of happened when I installed the trans coller and that would not show up in SD am I correct in this assumption
