Ok could this be because of a tps or some other sensors!? Or the fact that it dropped at the same place on both the dyno runs is it more fuel related i.e. fuel pump, etc.?

Im gonna wait to get my header to put that on cuz it will take care of the cat! And than Im going to possibly get new o2 sensors cuz when we put the 1.8 ecu on it took care of most of the problem except when its at full open throttle! I was reading that it could also be the MAF or TPS but I believe the TPS is new and we had put Wilburs almost brand new MAF on my car and it still did it!? The spark plugs and wires are brand new (bout a month old) besides its not even throwing a code!!

I think it would be wise to check the fuel pressure and go from there.

Well, if you're not getting proper fuel pressure it would narrow it down to pump, filter, regulator, or obstruction basically. Wish we had it on the dyno to test the fuel pressure while under load.

It's what controls your fuel pressure. On my car it's in the tank with the fuel pump assembly. I would have to look up where it is in your car but that wouldn't be tough to do on webtech. I think yours is set up a lot differently than mine though if I remember right. I think I know how yours is set up but I don't want to say something wrong before I look it up.
