Issues with my car.
 

Alright I'm pretty upset with my car. Me, my dad, and my friends have been looking at it, messing with it, trying to do everything to make it work correctly... but it isn't. Here are my main issues right now: after about 10 minutes of driving the air/fuel ratio will go over to lean and stay there for the remander of the driving session, the car tends to hesistate between the 2k-3k rpm range... usually when just driving normal speed, and now for some reason my boost controller isn't controlling my boost at all!

The only thing left to try to resolve the air/fuel readings is buying a new O2 sensor. Because when it says its running lean... it still seems rich because you can smell the fuel, plus I get crappy gas milage. We have messed with the Haltech and played around with the ignition timing at those rpm levels as well as fuel and everything.... and we can't totally resolve that. Even though we have been playing around with the vacuum lines... the line from the wastegate to the boost controller is fine and should be working right like before... but it's not. In turn... the turbo wants to spool up real quick and pull like hell. Plus now I hear my wastegate a lot louder than before, and less of my BOV..... weird stuff.

I would really appreciate some help and wisdom from you guys.

ill take ur turbo :)

How old is your O2 sensor dude? Once you replace that, you need to take your car somewhere to get it tuned... come on, you have a haltech ;)

The O2 sensor isn't that old. See the thing is, is when I got everything put together for the first time, the O2 sensor came with the Haltech and supposedly it was new. But my dad said sometimes they are bad new. So that's my only hope for my weird air/fuel reading problem. I want to get it tuned, but I don't know anybody that for sure knows about Haltech.
