After installing my boost gauge a while ago and getting enough guts to roll into the throttle all the way I'm seeing 10psi+. The boost comes up fast as well. I have been talking to someone at STS who had me check a couple of things and one of them being the spring color which is red and I guess signifies that the spring is correct for the STS base kit. All my hoses and wiring are correct as well, I've sent STS pics of my install and all check out. The thing is for three days after I installed the STS all was well, it ran fine, did not break up at high rpm like it does now. It did shift kind of lazily into second at very light throttle, like the converter was not locking up. I have been driving like a puss for three weeks now and have all sorts of geezers and yuppies blowing by me everyday because I've been so reserved driving it. Now I need to fix this overboosting condition and move on to the transmission which has either been fried by the over boost or the tune. Is it possible that the tune caused the trans to slip, or was it the over boosting? If you want more on the trans my post is in the drivetrain section, and I'm really hoping the masters here can help me out. Like I said in the drivetrain section, I can handle the critisism and know I was a dumbass for not having a boost gauge on from the start.
So let me have it guys, good and bad.

 

If you cranked up the line pressure, then it could definately have been the tune.

Are you running a boost controller? Check your vacuum lines back by the turbo.

 

Im not too familiar with the kit, but I would try two things
1. See if STS will exchange the spring for you just to totally eliminate that as a problem
2. Go through all the piping looking for something not lined up correctly and causing a restriction.

 

are you sure you boost guage is working properly...what does it read just driving normal and at idle

 

I told you in one of your other posts, mine was the same way, I was making 8-9 psi, and it would touch 10psi shifting to 3rd. My quick fix was to cut the wastegate spring down some, I will replace it with a new spring soon, because when you cut it, its no longer flush on the bottom and puts more side load on the valve.
Its not really sts fault, because the springs are all going to vary, and each engine is going to be different.

 

Also on the trans, I put a shift kit in mine within a week of installing the turbo, shifts great now, but before it was hanging or slipping into gear under any kind of boost, turbos make so much torque. As for light throttle, get a shift kit (best), or tell Allen to bump up the line pressure some, might help.

 

Just a side note, Transgo makes an awesome shift kit which I love (night and day for my truck)

 

ssssooooooooooo whats wrong with making more boost????? Just get a new tune. Isnt more power what we are all looking for?????

 

Make sure your boost reference is going to the side of the wastegate, not on top.

 

I have no blow off valve or boost controller and will most likely get one soon.

I want 5-6 psi now because I know this turd of a trans will not handle much more.

5-6 psi is what I wanted to start with so I could afford to get the rear end updated, not new injectors and a fuel pump to boot. Which most likely I will need to get it all safe and reliable like everyone else has already done with an STS kit.

My line for the boost reference is and always has been installed corectly.

The boost gauge is working perfectly, I have it plumbed to the bung that you snap off on the passenger side of the manifold. And my vac readings are correct at idle and cruising speed as well.

STS is trying to figure out what is wrong for me but that kind of hard to do from accrpcc four states. They said they would exchange the spring if it was the wrong one or to just make sur. It was the red spring which signifies the corect spring for the base kit.

My lines are all clear and have been checked twice for obstructions. I even changed the oil return line so it did not have even the slightest bend or kink in it.

To top it all off the exhaust inlet to the turbo has had a major leak since day one which has finally been welded this morning. (as all of the STS users know the pipes do not seal up tight and need to be welded) 10psi with an exhaust leak!!! Man boost is going to be even higher now that its fixed.

And finally thanks for the feedback and keep it coming guys!!!
