Amount of boost made?

[gilmerd89]

Hey, I was wondering if anyone could help me out. I bought a SRT-4 two weeks ago and I have noticed that the boost has not been consistent. It will make more boost some times and less at other times. Can anyone help me out with this?

The stock computer regulates boost based on certain variables...such as outside temperature and etc. So that is perfectly normal.

ok when im riding at like 60 and kick down a gear it spikes up to 20 + psi could this be a problem with my manual boost controller or my agp wastegate actuator

What are your other mods? Also, how do you have your vacuum lines routed?

[gilmerd89]

The mods are just AGP waste gate actuator, bov, manual boost controller. Vacume lines-there are two that are unplugged that come from the vacume switching valves on the air box. Both come from #2. Could this be my problem, if so where do they go and what do i need to do? And I think the AGP Wastegate actuator may be improperly installed, could that be my problem?

With just those three mods 20psi is way too much. Try setting it to spike 16psi. Also, having a manual boost controller and an agp wga is unnecessary. Now having an electronic boost controller and an agp wga would work so you could have low boost(for driveability) and high boost(for the track). What you need is just 1 vacuum line coming from the wga to the back of the turbo.
