Got a problem with new set-up. Help!!!
 

Ok guys I put my new set-up on about a week ago and everything seems to work fine. Turbo spools up at a pretty good RPM, whistles fine, etc....

The only thing is that my WG has a 7lb spring in it but my boost guage and Freelog both only read 4psi at full throttle. Along with the diffrenece in psi my Greddy Type-S BOV went from sounding like a high pitched sound to the sound a horse makes with his lips.

I checked for leaks and nothing ( exhaust and chrge piping). I also tried tightening the BOV but it made no diffrenece. Please help a brotha out.

I don't understand everything was fine when the Greddy kit was on. Thanks

Set-up:

Turbonetics Ball-Bearing T3/T4
Turbonetics Deltagate II WG
LSD motorsports Log-mani
LSD 2.5in DP
LSD Atmospheric Dump Tube
Customcoach intercooler
2.00-2.5in charge piping w/ authentic Greddy Type-S BOV
2.5 cat delete and 2.5in exhaust
DSM 450's
Xenocron chipped ecu w/ crome free 11psi map ( only running stock setting)

recheck vac lines. Are you sure the wg has a 7lb spring. The horse lip ---- seems like compressor surge. Bov is probably not opening up, again check your vac lines

where is the wg hooked up to...if its not on the intake mani youre going to get different values from what the spring is set for

The WG is hooked up to the vacuume port on the turbo. Should I route it to the intake mani and plug the one up on the turbo? As far as the spring rate I'm pretty sure it's 7psi cause it came from a DRAG GEN III kit and was never messed with.

yeah, route ur wastegate vac source to the IM, and check ur vac line for the bov

Ok I got the BOV working properly but I'm still only boosting 4psi. I think the guy might have cut the spring before selling it to me.
