hey, am wondering if my vsv has an issue, normally my car would build boost slowly to 12psi in 2nd gear+, only reaching 12psi at about 6000rpm upwards.
but yesterday I did absolutely nothin to the car, and it begins running 14psi, boost needle shoots right up to 14psi and soon as I get on the gas. Is this a problem? any info or advice is appreciated. Its is basically stock with an HKS intake, gutted cat and a 3" exhaust from midpipe back. -------------------- 1994 Toyota Celica GT-Four ST205 Turbo 4WD, Black

Ok, It is responsive it max at 10psi majority of the time. But tonight I did a few pulls i got 11psi in first and 14psi in second onwards :S... but stopped shortly after. It seems to cut to 10psi after the engine has been running for some time. The pulls were done just after the engine was at normal operating temp. But after no boosting for a little while back to 10psi. I am almost now certain there is somethin going on with the tvsv. But I am also wondering if there is a reason for its behaviour, seeing that it has been known to limit boost depending on how comfortable everything is.
