my turbo would go to 10 lbs an than drop back down to 8 and then we took it to 12 lbs an it went to 12 an dropped back down to 8 what could be the problem??

is the turbo messed up? what could be the problem????

 

Boost leak, if it's going from 8 to 10, to 8 to 12 to 8. Or it could just be boost spike you're getting, and the turbo is really running 8 psi, but spiking to 10 or 8.

This is why little turbos suck.
