If I reset the ecu will all the information that has been changed be reset also?
Are you talking about a stock ECU here? You can't change settings on a stock ECU... elaborate a bit?

I'd make sure that your pfc didn't get reset (I'm assuming that you've done some tuning since you have a completely open exhaust). I don't know if pfc shows engine trouble codes, but if it doesn't - put the stock ecu back in and see if anything shows up.
Check the MAP sensor (like someone already said) and make sure it isn't unhooked.
If you have a fuel pressure gauge you can hook that up to test the pump/relay/relay (speed)/resistor/regulator/ect.

I have the same problem...but may car is also hard to start and it will not idle. It seems like the top two spark plugs wont spark, they are brand new. I also lost about 50 percent of my power. It all happened so suddenly...any other suggestions to what this could be?

Check your coils and just about everything else in your ignition system.

very weird i had the same problem after installing my power fc and it would seem like it was hard to start and almost seem like fuel cut or something with a pop sound around 3800-4500.i was looking at the little harness around the ecu harness . the 1 that has a relay and a blue connector and 2 white connectors.i switched the 2 white and looped them now it is fine.the car gets right up no problems except it takes 2-3 cranks to start. if any 1 has a pic how they should go please send me a pic.thanks, jason lgjp2631@aol.com

Had the same problem exactly. What you need to change is the metering oil pump. Before i changed it i tried everything, everything was fine......
Change the metering oil pump and you'll be flying again........
