Where do I get an obt2 code reader and how much are they? I'm scared to drive it anywhere!

Ok, i'll go get one and see what it says. I can't imagine anything serious being wrong, i'm so confused with what it could be.

Ok, i'll check. I've already done a pretty thorough check! I did accidentally pull out one of the ecu plugs while the battery was still hooked up.

I bet when you tapped the O2 sensor wires for your TT you did so incorrectly.

^ +1 I was just going to mention that.
Try disconnecting the TT and reconnecting the o2 sensor. If your o2 sensor is not right your car will run horrible.

My car was running fine with the TT installed though. I read the code and its P0203. Injector 3 is open. I'm guessing it's means it's wide open, that would be why my car is spitting out tons of unburned fuel.

It runs poorly all the time? Idle, part throttle, full throttle? Take the EGT guage out and make sure all of the probe is still there.

Did you mess up the line going to the wastegate? If so you may have overboosted and hurt you're motor.

Good luck bring it to a shop interent diagnosing is hard.

For the gauges I tapped 3 wires into the cig. lighter, and then for the power I tapped into a wire out of the ecu. This wire is pin # 80 and has a constant 12V source.
When I installed the TT i had to tap into 2 wires, one for the ground, one for the O2 sensor. Any help or tips would be greatly appreciated!

John

why didn't you just use the HKS Harness for the Turbo timer?

I honestly have no idea what could have gone wrong. Run fine before you installed the gauges, now it doesn't. Did you make the connections to the right wires coming out of the ecu? Maybe you messed up one of the other wires coming out of the ecu. I got the smoke and the bad running once when I forgot to tighten one of the hose clamps on the intake and the pipe blew off. Just my thoughts.
