Um, so anyway. I too am thinking it's the tune. I'm positive it's not TM, that has been totally removed by Allen. He too said it sounds like i'm dumping too much fuel. I need edit bad. Well, and I need to learn how to use it. Where can I buy it?

Allen won't re-tune it for you? That's strange, I would think he would, he seems to have good customer service. You should ask if he'll re-tune it before you go and buy edit.

If you took it to a dyno they should be able to wideband it for you and you could then report back to allen and have him make some changes. Do you have access to a scanning tool?? With Edit you will still need a scanning tool. HPTuners has both. That is where my money is going..... if this laptop that I paid for 3 weeks ago ever gets here.

damn, hef. my 4.8 EC won't do crap even when powerbraking. maybe the g80 is not helping...and the fact that it is almost totally stock still.

He'll retune it for me, but, I need to be able to accurately tell him what the problem is. Right now, and for the past 10 months, I haven't been able to.

Sorry your thread kind of got sidetracked. Hope you get it tweaked right...it should be somewhat of a beast.
