What other mods do you have, as far as air-flow mods. Like a cat-back, headers, intakes, etc.

i have a powerdyne 8psi supercharger, took 4 cats off, flowmaster 40 series, superchips computer programmer

just an hpipe? i wouldn't say more then 3-5HP but your sound probably got much deeper with the cat delete and midpipe. go for some long tube headers and you will see 15-25HP increases!

lol make sure to post your mods when you post for wanting to know how much hp/tq it added. On a stock car you will lose a bit of backpressure, perhaps drop the dyno peak numbers down a tad but have it a little fatter on the top end~

With a blower and 8psi you should pick up 5-10hp~ and tq.
