going nutz please help. have little time. I have a 5.3l with a 4l80e and 76mm turbo swapped into my buick regal. i have had major idle issues as when i start it it want to rev to the moon. right now my trans is bad and is always in gear so the only thing stopping it from reving to 3000rpm is the trans.
i just converted it to 2 bar os and it still dose it. funny thing is after checking another car with the key on and engine of my the map should read 98kpa, in order to offset it correctly i had to set the offset to 24 which is real high. and the linear to 200. when i believe it should be 200/10.33 offset.
i have tried another brand new map and i have the same problem.
now if i completely disconnect the map it will idle and rev normal. just really laggy. below is a list of spec and tune and log.
5.3l
4l80e
76mm turbo
e85 fuel
80lbs seimans deka injectors
bosch 044 fuel pumps
2 bAR MAP WITH 2 bar os
all wireing is new
pcm is questionable
hp tuners

I am wondering this also.had my truck tuned by a rep. Tuner here and every time i start it up it revs to about 2k 2100 for a sec but drops rigjt back to normal and idles fine.we have checked everything good and had 2 gm techs at my work also for leaks or anuthing and theres nothing.my tuner tells me everytime that i have a vaccum leak and thats the end of it.so as of right now i deal with it bc idk what else to do.

please help Is what im asking to much?
Did I not log the right stuff?
Im new at this and would love to drive this car someday before I start chemo.
Please if im going about this wrong please speak up. I will correct my error.
Iv searched and search. Replaced all gaskets on the intake. Picked up a new intake and swaped it to with new gaskets.
All I need is some direction please help.... iv even posted this on hp tuners board.
I can get it to idle low with the iac unplugged. But it stumbles off idle.
