Thread: Erratic boost........
06-25-2013, 04:11 PM #1
Hey guys, wondering if you can possibly give some insight on a problem I'm having. My boost is low and erratic out of the hole, once I'm up and going it revs out and the boost gauge (factory) is pegged. It's only from down low. Sometimes half boost sometimes 3/4 then it pressurizes and goes. Sometimes there is a delay and then the boost will hit full. Can it be the tune? It ran fine for a few hours and and then this came out of nowhere. Seems like the throttle body is closing almost like the torque limiter is kicking in. R&d is scratching their head also
HELP! I'm going nuts.

Check the I/C sounds like a leaker.

its ez, pump air in where the water usually goes and IMO about 30-40 psi
then fill the part were the air usually goes with water and if you see bubbles you have a leak

Seeing how boost is locked to engine RPM if the clutches in the charger are set to slip correctly it would lead to possibly a mapping problem with the reflash. How are you monitoring boost? Check the hoses for leaks, engine mounts (engine could be shifting pulling on the hoses. What do your WOT RPMs look like, are they low?
