sts kit with intercooler from trt build forged motor and all with tune,42 pound injectors,walbro 255 fuel pump.

Where is your boost controller referencing for a boost signal? How do you know for sure you aren't getting boost (boost gauge, scanner)? What size spring do you have in the wastegate?
Also, when I first got my intercooler, I kept popping the charge pipe off whenever it boosted. Then it wouldn't boost since all of the air was just going out to atmosphere.

Definately check your vacc. routing for the BOV and check up and down for leaks on both sides of the turbo to the motor. I had a decent size hole in my exhaust but it was still enough to to spool up the turbo but not create boost.
I would un-install the boost controller for the moment untill you get your boost issue fixed just so you know that you don't have another possible issue with another system.

last night my pipe that goes under the rear control arm blew off,is that signs that its getting boost but like to many leaks?
do you have pics of how you reference everything?cause per sts instructions they show no vac lines from the turbo nor wastegate going to any vac source

The wastegate gets it vacc. form the comp. side of the turbo. Make sure that the nipple on top of the wastegate is venting to atmosphere unless you have the boost controller installed. If it is installed you need to follow the install. pics to the T.
If you hooked everything up as the STS instructions stated you should be good. Make sure that your BOV vacc. source comes off a "T" from the brake booster.
If you blew off one of the pipes/couplers you definately need to check all of your couplers!

If you hook everything up according to sts instructions, you will probably only see about 3#'s off the wastegate spring, and this will flutter. You REALLY need to reference the wastegate from manifold boost, not the turbo. I am also confident that you have leaks somewhere.

My problem was that the pipe that goes over the axle had popped off and wasnt touching the pipe it was suppose to be attached to. Its kinda hard to see also

so hey, any of you tell me what the difference is between hooking up the wastegate from the compressor then the intake manifold? just wondering. how does it effect responsiveness?
and yes... i know... thread necromancer at work again lol
