I went to the track this last weekend and made 11 passes. My car was running okay for the first 9 passes but after that through 3rd gear it felt like a significant power loss. I compared traps and times and I lost about 6 tenths. Not sure what happened but to be safe I took the car home. Anybody recognize this problem? It is a bpu supra and made 362 whp, and my times went from13.1-13.3 to 13.7-13.9. They were all pretty consistent runs untill this problem. I have no idea what's wrong.

Could be many things.

Slipping clutch, boost leak, bad plugs, etc. I would do a pressure test first. Also, what was your boost set at during the runs? DId boost decrease at the end of the night?

boost was ok through the runs. Boost is at a little less than a bar of boost. It was only in the top end. Just trying to find out if it is something i should attempt to fix or take to the shop.
