Hi guys!
I have a problem with my Mustang... What I have on car and what have done:
2016 GT(MT) Base PP with Roush supercharger Phase 2 (BAP and 80mm pulley)
14k miles
X-pipe + Roush axleback (Cats are intact)
Roush tune (should be... bought car not a long time ago)
new roush air filter, new MAF, cleaned TB
93 octane only!
So when I am cruising or slightly pushing accelerator I am getting slight jerks that feels like misfires
On decelerating I am getting gurgling/popping sound from exhaust(like if there fuel is burning inside exhaust)
On idle AFR bouncing 13.9-14.3, on cruising 14.1-14.3
long/short fuel trims are seems fine
also accelerator pedal relearn was made after I've removed TB to clean it
No codes, no misfires
WOT - everything seems fine, AFR ~11.6, boost ~10-11psi
sometimes car jerks 2-3 times on first gear after full stop.
vacuum gauge ~22 on idle, so should be no vacuum leaks.
Please help! Don't know where to dig... don't wan't to start changing everything like it was on my previous 2007 GT ))
Maybe somebody experienced also can read my datalog(SCT BDX) for a reasonable fee to check what's wrong?
Thank you!
