What do ya think???

If I make a WOT pass with the converter unlocked, then the boost stays pegged on 20 psi. If I make the next pass with the converter locked, changing nothing else, then the boost climbs a pound or two and flutters, kinda like I'm feathering the throttle (obvious fluttering sound from filter). If I crank the boost past 21-22 psi and make a WOT pass, with the converter again locked, the fluttering goes away??? I was using the OE wastegate solenoid with a bleeder and thought this might be the cause of the fluttering, so I removed the WG solenoid from the loop and used only a bleeder.....no change. Seems as though locking the OE converter is creating enough drag to elicit 1-2 psi more boost, but what in the he11 does the locked converter have to do with the fluttering, any ideas??? BTW, this little problem was present with the OE turbo and WG actuator as well as with the new TE44 with HD WG actuator I just installed???

31 views and not 1 opinion/idea??? TTT

loop the compressor and wastegate and lose the bleeder....see if the prob goes away

I would think its the driver.
Hey, you asked.

How about the TCC chattering? Dont you have a 11.teen-11.oh car Joe? I bet you are seeing the clutch slip, and its loading/unloading the motor slightly enough to see flutter in boost, but not RPM on the tach.

Best thing I could come up with

EDIT: oh, I see this is a different car....could be the same deal though

Yea, my old GN now resides in Orlando, Florida with a happy new owner. I'm back to being slow again (and kinda liking it I must add), time to spend all the $$$ and skin pounds of flesh off my body to make this one fast. The TTA is everything the GN should have been as far as braking, handling, aerodynamics etc...are concerned. Thanks for the input though, it's definiately something to consider. The odd thing is that it only does it at 21 psi, not higher or lower???

One_Quik_6,
I would think it's yo momma

How about a flakey spot in the gauge? Or a leak in the vacuum line to the guage (that appears at 21 psi and is overcome when running > 21 psi)?

Scott's right.A small leak after the compressor outlet will cause some surging.Just went through it myself with my 63e/ V-1 combnce you get past a certain point,it goes away.
