no gain from headers
I think it goes without saying you need a tune after LT's on an LS1.
I dropped 4 tenths and gained 3mph after LT's, ORY, and a tune only other mods were a lid. I went from 13.30's to 12.90's with 2.0 60ft times.
I ran the car with the stock tune in it for a short bit and it was really rich.
Even after the first tune I'm still running a little rich 12.1-12.3 and need it tweaked a bit more. I can only imagine how rich my car must have been
running with a stock program.
better 60 ft times will defiently help your ET's but won't address the problem,
you'll be in good shape with your exhaust hooked up and a tune.

I have the same results which is nothing with long tubes
and no tune,recently I got a tune and there is a definite
feeling of more power I can hardly wait to get an E.T this spring.
My tuner also recomended that I get new O2's he said that
for performance driving they should be changed every 30k.
