Any updates on the cause of this 2500rpm stumble/2 step sounding issue?
2006 AWD 300C Turbo - bone stock pre-eagle 5.7, bone stock NAG1
10.6@127mph on 14psi - WatTuned
I'm having a very similar issue where my 2.9l whippled 5.7l hemi stutters when going wot from a stop. Right around the same rpm the car stutters 3-6 times like pedaling the throttle before finally taking off. Working with a diablo email tuner and he's tried everything and we can't get it sorted out.
Anyone ever figure this out?
Hey guys any updates on this. I am new here and have a 5.7 charger procharged, pushing 11 pounds, with holley manifold, fully built nag1 trans, 1200cc injectors fully tuned with correct charts fueling and timing, and no one can figure out how to get rid of this 2500-2800 stumble. It really annoying. Its like its falling on it face for a moment almost like its leaning out and then once it passes she flys. I will be installing a boost a pump next week but have a feeling that might not fix the issue. if anyone has a fix or ideas please share. Thanks
boost a pump ewww
which fuel pressure sensor did you add to log the data that suggests that the pressure is falling off?
i saw dudes video and it really does not sound like a pressure issue
he doesnt have a sensor tho
whats wrong with a boost a pump? also someone mentioned its in the car computer a factory setting that is giving off this issue to everyone. Dont know how true it is but it seems like alot of people with this set up are experiencing this issue.
any updates?
Has anyone figured this out?
update went to a different tuner and he started from scratch and fix the stumble issue. Car runs like a dream now. Call Jim at True Street Performance in bayshore NY. totally worth the drive.
