Surging........
Okay, i little while ago, i poasted a problem with surging, and was told that it owuld be resolved as my chip learned my car, and that would take around 3 weeks. Well, it has been over 3 weeks and the problem is only more noticeable...get a drink, cuz here it is:
If i am a gear, namley 3rd and up, and i am driving in the range of 2-3k in 3rd gear, and more so from 2-3.6k in 4th and 5th, and i press the throttle a concideramount to full, the car las a slow acelleration (which is expected at that low RPM), but once the boost gets around 8 PSI, the car starts to surge in a fast rough matter, like the power is comming on and off, but its rapid, almost to the point of a vibration, but it is kinda random but continuous. From there, the boost keeps steadily gaining, and it seems to be normalbut the surging gets worse (and keep in mind, this is a conciderable throttle). It calms down around 3.6-3.8k.
Now, if i am to let off the throttle before 3.6-3.8k, say at 2.8 or 3k (but anywhere in the range there works), and i slowly let off the accellerator, it keeps surging until just when the boost is about to drop (meaning my throttle wo;uld rev the engine lower than the transmission is moving it) it gets a surge of power, but it isnt rough, its like all teh sudden it has a 5 hp boost, and that is right before the boost goes byebye from letting off the accellerator.
Now, i understand if what i jsut wrote cna be a little hard to follow, but try please. Its seriously Pi$$ing me off.
I have a 2001 Audi A4 1.8tqm with APR chip and Borla catback and modded airbox (this surging started before the airbox mind you)
