I got a phone call from Cajflynn tonight and he's got a shuttering problem with his truck. I'm going to relay this phone call the best I can. So let put our heads together and help him out. He got some internet access on his phone...
SIGNATURE of Cajflynn truck
2001 qdlb, stage 2 f1 injector, 3 disc tc, 4 inch exhaust, arp head studs, ats co-pilot, power puck/smarty, j-hook, lots of gauges, lots of mag-hytec, bhaf, vulcan big line kit, 762K miles
Conditions...
Mild hill climbs at about 63 MPH steady or acceleration the problem (shutter) occurs right at the crest of a hill. Auto Trans temp is <100*F and the rear end about 125*F. Pulling about 800-900*F worth of EGT at 18 PSI of boost. Currently towing about 5K pound trailer.
Now The power puck is traded out with the Quadzilla XPT currently but is shutters the worse with this combo at about 63 MPH. The smarty is in fuel only mode. Trade back to the puck and its not as noticable but still there. But the strange part that the shutter is only notice while towing but empty he's got no shutter. Trans is in good shape...
He's also wondering if the APPS sensor is the cause of this? I got a feeling no... (IMHO)
