Running rich & ALOT OF MODS

[TonyStarks29]

Ok i have a 1994 240sx Vert with the Sr Black top my mods are

Gt2871r740cc injectorsFMIC Tuned ECUHks knock off bovZ32 Maf

My car is running rich at idle i figured it just needed a tune..

my car was idling at 1300-1400 rpmafter tune im running1-1200 rpm the tune deffentily helped it go down but now its still up there

i cant seem to figure out the problem i've tried to reset the throttle, checked for vacume lines im thinking maybe its the Maf but i doubt it...

could the 740 injectors be too much on my car? (wouldnt the tune fix that)

any ideas would be great...

The knock off BOV could have leaks. I would change that asapJust a thaught....

check all the vaccum lines again, for a leak,

or put you maf right before the throttle body for an accurate read.

ECU tunes usually run rich. You'll need a piggy back fuel controller like the Apex'i SAFC to fine tune.
