Just in general as soon as it moves, i have a lightly modded na and it seems to accelerate about the same if not a little worse. Which leads me to believe the motor itself is fine. At about 6 grand its like i just flat out let off the gas. Its got a manual boost controler in it, i would like to find the diagram of where everything is so i can hook the gauge up and get a rough idea of what boost i running.

Its for sure an aftermarket cat welded into the straight pipe about halway between the motor and the muffler, which is also aftermarket. Dont have to worry about emissions where i live, but all the emissions are still hooked up.

Im going to run some water through it per rotary ressurections site directions to clean out some carbon.

So I highly doubt that is an accurate statement--Though I very well could be wrong in that assessment.

Well i have read a lot of stuff that turned out completely wrong so.......lol

Consequently if you're not familiar with the car itself it helps tremendously to know what has been replaced on the car and what is not specifically on the car from a normal one. Beyond that welcome to the RCC.

Been here for a little while just not real active lol, and yeah im in the process, it has a manual boost controller, turbo timer, what looks like a fcd zipped tied next to the pressure sensor, ill get a pic, and an electric fan, i want to take that out and go back to the stock clutch fan, its wired to stay on as soon as the key is on.
