i just put on my rage header. but when i took it for a test drive i dont feel any gain at all. would i have to go get it tune to expect gain? the motor i got is a gsr. with jdm type r piston. ctr intake cam. sk2 manifold. custom 2.5 cat and chip p28

 

I would expect somewhere in the -10 to +10hp range. Maybe you should tune it and see what type of numbers youre putting down....

 

yea tune would def help most gains will probly by had in the top end

 

tune

 

you guys think that i need to upgrade my fuel system. like pump and injectors?

no, you arent making that much power yet

 

What's your exhaust setup?

Untuned, the rage header did little on the butt dyno except for a bit of midrange. Once I added on the full 2.5" exhaust however, that's when the butt dyno recorded a record high all over.

 

i have a custom 2.5 with a dynomax exhuast with 2.5 inlet and outlet

 

tuning man, just go have it tuned and you'll definately see gains... 2.5' collector i'm assuming too right?

 

are you still running gsr gearing?

 

Yes its a 2.5 collector and I'm running with a b16 tranny
