What HP should I expect from these mods on my Evo IX on a dynojet or mustang dyno? K&N cone filter with vibrant maf adapter, Megan Racing Downpipe, TTP Resonated testpipe and megan racing catback and tune?

 

If you add a tune, mbc, walbro fuel pump...expect about what I have...if not, well expect lower

I forgot to mention that I do have a tune.

 

Thanks.

 

Personally I would have waited untill I had more mods before I got tuned...I got mine tuned because my intake is funky until tunage is done and because my walbro was running too rich...other wise I would have waited

Everyone have told me that you need a tune after a intake. Thats why I got mine. Beside even on a stock car a tune can make good power.

 

Yeah but it can get expensive to tune and tune again
