My mods I have are JWT intake, Crawford plenum, Crawford headers, Topspeed testpipes, Borla exhaust. I had the Crawford cats on, but swapped them to testpipes to see how far I could push this engine without anykind of tune. I didn't do the A/F ratios, but now wish that I did just to see if the testpipes helped lean it out some. I know that someone will come on here and say the dyno is messed up and the numbers are bullsh!t, but I really dont care if you think that. The runs were all done on the same dyno and this is what I am going by. The numers are SAE corrected on a Dynojet.
Green = stock
Red = JWT, plenun, headers, highflow cats, exhaust
Blue = Mods listed in paragraph (swapped highflows for testpipes)

Thanks for all the comments guys. Eventually I will get the UTEC or Emanage Ultimate and try to get over 290rwhp. 300rwhp would be nice, but that is kinda a big jump from 282rwhp. The baseline was a big shocker to me and also to the STI with exhaust that I ran with
. I love the power the testpipes gave me over the highflows, but the rasp is killing me and I have to do something about it.

Nice numbers!
If I was you I'd swap the JWT for a CAI, get a full set of pullies, a grounding kit, a nice set of cams with springs and retainers, then do your engine management... You'll definately have over 300rwhp.

These numbers look really good. I got 280rwhp with Nismo cat back, Nismo CIA and a Unichip. We did add a little gas to make the mixture 12.8. It was lean above 4k rpm's. Thanks for posting this because most people don't believe the numbers posted with the rev-up motors. Great job!

Wow those are great numbers! I would love to go with test pipes as well but I think the raspiness would kill me as I commute almost a 100 miles a day through Socal traffic. I may be considering resonated test pipes but we'll see. Ill be dynoing my car soon as well as I have got some new mods done but congrats on those numbers!

Does anyone know if the resonators would hurt power at all over non-resonated?
