I have an 09 VMAX that i recently straight piped. Next step is the cold air intake....does anyone have a similar set up and has seen a dyno? Im assuming i'll see some kind of gain with the new set up but does anyone know approximately how much? I have HP tuning software installed on the truck too so i could set up the computer for the new intake/exhaust.....altho i don't know how :S

 

should see about 15-20 more hp, but the key is in the tuning.

 

When mine was just straight piped and i had cold air and a mass air flow sensor, and tune i put down 325. With the headers and a re tune i put down 365

 

i find straight piped you lose low end hp but when you go to a cam, supercharger youll see a gain. if i was you id atleast put a muffler on it to keep the noise down

i have LT and a ORY but i feel im losing low end tq but itll help when i cam an supercharge after its paid for

 

when your racing after that first shift you will be around 4k which means all you want is high end power, you will see your track times go down alot.
