How much gain from 4# to 6#?
I went to the track this past weekend and ran my best of 12.7 
I am currently running a 4# lower and wanted to know how much can I expect off my ET if I switch to a 6# just for the track. It seems I am know at the magic point where it is going to be a lot more $$ to start getting any noticable gains. I feel the pulley upgrade would be the most cost effiecient. I am open to other suggestions. Current mods are in sig and I do run ET streets at the track.

I was running 12.7's all day with my 4# pulley. I installed the 6# Metco lower, sent my chip back to Mike T. for reprogramming, and now run 14.41 @ 110 mph, and have run 12.43 at 112 mph.
So to answer your question, I took off .3 with the 6# and a good safe program.
I drive the truck on the street and the 6# has not caused me any adverse effects. Except that I only got 14 mpg on the 260 mile round trip to Pittsburgh yesterday.
Hope this helps.
