i got my 2000 pontiac sunfire in august of 2004 it has the 2200 with a 4speed auto transmission and ive noticed that i have lost a lot of horsepower since then and i dont know why i use to be able to burn out and hit the speed limiter easily but not anymore i cant even chirp my tires when i take off and i cant even get up yo the speed limiter anymore i can barely do 100 mph and i dont know why its doing this ive done all the oil changes on time and everything ive done tuneups and im still lost and there is only 80,000 miles on it so if you guys have any ideas on what made me lose all my horese it would be awsome thanx in advance

1. You need to grow up and stop doing over posted speed limit. Your gonna kill somebody....
2. Its a STOCK 2200 Automatic //// Your car never had horsepower.
3. IBTL
4. Have a nice day!!

Assuming that you are doing this driving at the track, how different are your times? I's assume 1/4 mile since you hit your limiter? How's your 60' time? Decreased or stayed the same? What about your trap speed?
