Default Experts inside

My car has been putting down very low dyno numbers, 376RWHP and 346 RWTQ. I have ARE stage 2 heads and TR224 cam and all the boltons. The car has been tuned with LS1edit, so I dont think tuning is the problem. A few people have told me the problem isnt the head but I am not sure. Also the horsepower drops like a rock at 6400 RPM which isnt normal. What do you guys think, is my engine shot or is it the heads. It was almost as strong before I did the heads and cam, intake pullies and tuning. With all my mods I only picked up 3 tenths and 3 mph.

Before with Headers, exhaust, lid and converter I ran a 12.3 at 110.9

After heads and cam and all the mods in the sig, it ran a 11.98 at 113.0

that's not easy. I don't want to say it, but is it driver? See if there is someone you trust that you know is a good racer can wring it out for you. Not trying to put you down, but something is wrong if you spent that much and now go 3mph faster.

You sure you were not detonating up top? Put a scan tool on that monster to see if you were getting KR.

I really dont think it is the driver, first of all since its an automatic and second of all since I drove it to a 12.3 at 110 with just headers and converter. And no it isnt detonating up top, I have all the logs saved from the track and It is running perfect.
