Alright I installed Hooker Longtubes a couple months ago, and I put the O2's into the headers at my exhaust place. I took the cats off, and am just running through a cut-out. I ran an 8.8 (1/8 mile) before and I just went to the track and barley ran a 9.5. It barly takes off, and taps the rev limiter. I just had the trans rebuilt for the third time and only have 78000 miles on it. I took some of the !air stuff off and some egr but didn't plug it. Could bad 02s cause this? I think I am running rich because my exhaust smells and it pops sometimes.

thanks in advance;

So many people seem to slow down with LT headers on nearly stock cars.I dont get it

 

I gained 20RWHP with my LT's.

 

You removed the EGR and A.I.R. system and didn't plug the holes? If that's the case you're driving around with holes in your intake from the EGR and as a result have a bad vacuum leak. That's your problem.

 

If you didnt block the egr then you car will not run very well at all.
