TEA stage 2 vs stock 243's
 

anyone ever do back to back to see how much was gained either at the track or the same dyno? I might get a set and am trying to see if I can justify it..
my car 302cuin bla bla 9.55@148 on a soft 1.58 sixty..
im pulling the heads to change lifters from the ticking ls7's to some comp magnums and my buddy is trying to buy these from him for 1k.. is it worth it?
or I can get some afr 255's for 2k but at least this have a better deck than stockers..

no one has run back to back with boost with these?
