Well guys I'm back form more issues, well here's the story I tried installing my Greddy Profec b II and I thought I had it right, well anyway I had the COM hooked up to the top of the WG and i thought i could hooked up the NC to the back of the intake manifold, well it turns out its sucking instead off pressurizing the WG so the WG opens when I give it any gas, I must of the installed it on the WG wrong. Then i gave up on that and disconnected the Vac lines from the WG, but now my car is really acting up as in I think i'm over boosting or something. I seriously give it about no gas and the rpms and boost shoot straight up and the car is going 10 mph.. shift in to second same thing but I go a little faster maybe 20 mph, by the time I reach 5th gear I'm going 50 mph but if I just put a little on the throttle my rpms shoot as does my boost, could this be caused by a boost leak? Trans? It didn't sound like there was any slippage and it was shifting just fine. My car has been very troublesome since I have bought it, I just want to drive it with out any problems...
 
AT or MT? Are the RPMs rising inconsistently with speed? And when you say boost shoots up, how far are you reaching?

It is a MT, Well I put in it to first and even all gears, I can move if I don't put much on the throttle but when I put just a little more down the rpms and boost sky rocket.

I know yours is a N/T(with turbo), but you'll get the same concept

When it says teed from the wastegate to the housing does that mean turbo? I have a t3/t4e in my car and it does not have that nipple, I could take a pic if it would help you help me?

Post a pic so we can see how you have it right now, if you don't have a line that runs to the turbo then you have to T it off the bov line which I wouldn't recommend doing. You can tap a fitting on your turbo housing so you can run a line off it, then you'll be set. I actually currently need to do the same thing haha, I'm t'ed off the bov right now because my J pipe didn't come with a vacuum fitting on it, I haven't had any problems with it but people seem to think its more reliable the other way around. I haven't found a difference in either as my 1G is ran the "correct" way.
