I made passes with the old setup which was a .90 housing with 40 overs. 60's are better now than they were then. I do have more experience now and tuning is probably a little better. I am running a 1.10 housing now with 100 overs...Damn. She really catapults off the line! Its gonna be a hard decision. I plan on running a b375/87/.90 Bullseye.
Did you make any passes before switching the exhaust housing?
