Well I finally finished building and installing my turbo kit, however I am having some small problems with boost levels. It spools up fine and reaches about 7-9 psi then once i enter the higher rpms it dies off to about 5-6 psi. So im wondering what is the stock wastegate actuation of the 13g and why do I have this boost spike / drop off. I have already looked for any boost leaks and fixed the small ones I have found however it did not seem to fix the problem, mabye I just need to spend more time with the soapy water seaching for any other leaks. Any info would be much appreciated, and thanks in advance.
Here's some info about the setup if your wondering
95 Avenger
Log style manifold
13g turbo
open 2 1/5" downpipe (for now)
DSM 450cc injectors

2 1/4" IC piping

have you tried the wastegate acuator mod??

I myself am running a 13g setup
