ok so I am new to this blog thing, I currently have a 08 EVO X GSR, list of mods I have are as follows:

ACT heavy duty street disc clutch
HKS BOV, Downpipe, straight pipe, legamax exhaust
Injen shortram intake and intercooler piping.
*Not tuned yet. everything else is stock from factory

I can definately tell there is a difference performance wise, I have tried to look online to see what the power gains are on each part. but have not had any luck in finding stats. can anyone tell me what I should expect after putting on these parts?

any reccomendations on what I should get next? or any other parts I should get installed to make current mods perform better?

 

FMIC maybe, most definitely a tune though.

 

Once you get a tune, you'd probabaly see a huge difference. Maybe sell your legamax and get a larger exhaust. The legamax is near stock in terms of pipe diameter.

 

I def plan to get it tuned after i get a test pipe sometime next week. I like how the legamax is quiet but still performs though. the only time i can hear my exhaust now is if i am at a stop.

 

you can expect crappy results and wasted money without a tune. Accessport FTW :bowdown:
with a tune, probably ~75hp/~100tq

 

answer your first question. rough hp figures.

0hp ACT heavy duty street disc clutch
15hp HKS BOV, Downpipe, straight pipe, legamax exhaust
20hp Injen shortram intake and intercooler piping.

testpipe adds another 10hp

240whp stock. now 285, tune raise boost 340whp

easy 100whp gain.

 

you could benifit most by getting a tune from a reliable shop in your area. no mail ins, no frinds who "know how" to tune etc.
