wastegate problem?

[92boostedty]

every time i try to leave with boost when the ty goes to shift out of first it seems like the wastegate sticks open? and i have to let off the gas cause the truck isnt going anywhere...but if i just get on it hard it goes fine. is it the wastegate? what can i do?
thanks

so it won't shift out of first? I don't understand your problem. Doubt its anything to do w/ a wastegate though.

Re: wastegate problem?

if its making boost and not going anywhere it sounds like your tranny. Chances are if you have a wastegate problem it will either overboost due to a cracked vacuum line or be stuck at 8psi due to a selenoid or the wire being disconnected from the ecu (low boost can also be a leak in the charge pipe), but in either situation it would either stay high or stay low, not drop at a shift. If it is detonating REALLY hard it may pull back enough timing/boost to see a drop depending on what chip you have but you would hear it rattling.
