stalling at idle ± timing
 

Okay, why does my recently boosted 03 eclipse gts, stall at idle...? also, w/o the MAS it will almost stall right away but then, even out.

second ?
which way do i tune all the timing an fuel maps for when my charge pipes are still in vacuum at low rpms? im thinking this may be the problem..?:confused:

i would say theres a vacuum leak. does this car have a maf(mass airflow sensor) or a map (manifold absolute pressure) sensor?

what are you using to tune? you dont need to worry about non boosted tuning if your using a stock ecm and reflashing it. if you have a standalone ecm( which i doubt) then you need to build the fuel and timing map throughout the rpm range and that is a task for an experienced tuner.

i have a MAF, there is no vacuum leak i can find, and i had a small boost leak but its fixed now...
i thought the problem was getting better but its not...

i might end up taking it to a import auto place to take a look at.... i almost stalled turning on oncoming traffic today, they are going to open the hood and say HOLY ---- WTF!! lol
