    If you wanna meet up im off the next 2 days so hit me up and pick a spot. We can chat and u can take a look at my setup. Its not running as good as it should as the tune is a bit conservative and I have a egr leak but the tuner box is on the way and im going to delete the egr.

    Re: New Guy - 05 Grand Prix

    Yes I have ordered a shift kit and fuel pump rewire kit and a DHP tuner box. After that im going to drop a pulley size or two and possibly put a intercooler on it and that's probably as far as ill go. Maybe a performance trans when I blow the stocker.

    Hitting the Dyno

    Im going to see Ed tomorrow because I don't think my tune is set up right. I need a baseline of what the car is running @. I have a AVT box on the way and HPtunr software to fix the current tune. On the low side I should be @ 260 to the wheels and at the high end 280. Any advice from anyone that's used Ed before?

    The biggest problem you'll have is getting a proper o2 reading. So on the off chance you have an extra oxygen sensor hole then talk him into using it for his gauge....

    Re: Hitting the Dyno

    Yes I have 2 extra bungs but I rtv'd the shit outta them. I don't plan on him tuning it at all though. I deleted the downstream one from the ECU so its an empty bung and I moved my upstream to the crossover so I have a bung on the downpipe of the rear header. From the scans ive done im running pretty rich my LFTF's under WOT are anywhere from -7 to -3 at the lowest

    Re: Hitting the Dyno

    .....you mean ltft? And that doesn't make sense because it will be in open loop at WOT and there will not be any fuel trimming. Run his gauge...at least you'll have the o2 reading on paper
