VERY slight negate TPS voltage. BAD? The hole in my Tbody blade is a little too big and is causing my IAC counts to drop to zero with the TPS at 0 volts.
I adjusted the TPS screw and did a reset but the voltage now reads -0.4 to -0.8 and the IACs are now in the 11-17 range and the idle is solid. Even if I adjust it a 1/4 of a turn the IACs get too low again.
Are there any negative effects to having the TPS read VERY slightly negative.
If not I'll leave it as the idle is great now
Chris
ps- My LTRIMS on left and right bank vary. One bank is -11 and the other is -4 LTRIMs STRIMS are between -2 and zero.
Have you guys seen differences like that before?
thanks!

as long as the TPS blade opens 100% you are good.
AND
the TPS 0% - 100% works by gas pedal = good
Why dont you just raise the idle?
And yeah everyones car has variation from bank 1 to bank 2, its probably the header design more and general car variance, thats why the system is in place to compensate.
