I have a 05 with the following:Hks dp,rmr 3"cat back,rmr intake,hks 272's, valve springs and retainers,cam gears -3,-3,and ecutek tune. I am only making 270 hp on a dyno dynamics dyno. I am tuned on 93 and boost is solid 22 tapering to 19 at redline. Is there a mod that I have overlooked or does it just sound like a tune that needs improving.
p.s. I know that I need to get rid of the cat but even then it won't gain me more than 15hp. I think it is still low.

 

do u have a MBC? i mean if u did then the boost should hold 22 or 21 psi strong till redline???

 

no need ecutek controls boost

 

Isn't the HKS 2.75 inches? Get a hi-flow cat, port and coat manifold as well as the O2 and your 10.5 hotside. Then get alky injection with the lower I/C pipe.

 

don't dyno dynamics read low? is that custom reflash or through the mail? its probably about right if dyno dynamics read low

 

an MBC still provides higher boost and holds it better than a flash. I can't imagine relying on a flash to control boost when you go so far as to have cams with upgraded head internals. That's weird, because a nice MBC is only $85 whereas all that other stuff is over $1000 itself...

DDs read really low to begin with, and 15whp from removing the cat is a big jump, too.

 

I had a mbc on my last evo and are aware that they are a great way to control boost. From my experience ecutek controls boost just as well, and since I don't ever run race gas I don't need the adjustability of a mbc.
