Sup,
Just upgraded my **** to new injectors and MAF, re-tuned by Overkill (Scanned on, but canned tune still, I know.. I know..)
Mods are as follows :
XP Cam, SD Headers, 3.4 pulley, 4" intake with that big MAF Will have, #50 injectors, 180* and 104's gapped at 0.050.
My issue is mainly, well I'm trying to figure it out.
LTFT's are pegged @ 16.4% all the time beside at WOT, where they Lock in at 0.0.
STFT's at idle are 0.0% and bounces a bit between -3.0 and +3.0.
Driving they will wander about -3.0 and +14 ish.
O2's narrowband volts will be between 0.820 and 0.850 @ at WOT, which is lower than they were before the upgrade.
KR is higher than before too.
Now I know +16.4 is nearly always vacuum leak, first thing I did was carb cleaner all around, reseated injectors, cleaned holes SPOTLESS, no leaks were found that way, tried propane, nada. Lastly smoke tested the engine, build a presure in the motor with smoke, nothing came out at all.
Now I remember that on a vac leak, STFT's will bounce up to +25 too, when on my case they stick around 0.0 idling.
I am seeing with Will right now for a re-tune, as this, to me, might be the issue right now.
But if any one here has any other ideas, I'm a taker!
