here is a dyno graph of my old set up vs my new set up. for those who wants to know what a stock k24a1/k20a2 frank make over a k20a2. it seem like k24 high end suck, but low to mid is awesome.

not bad, you would still stomp all over your old setup. Vtec engagement still needs to be lowered a bit, too big of a jump at 4200-4400rpms

what other mods?

RBC
kpro
3in CAI intake
BCRH
2.25 pipe w/ Twinloop muffer
650cc

its not fully tuned, just a simple street tune until i can save up money for a real tune. My AFR is about 13.0-12.1 is that good for my set up because that is a bit rich.

forget top end on the k20/24 build. You make the peak power so much earlier its a thing of beauty.....

I would say that is pretty good for your setup. It is running a little rich so you could lean it out a tad, fix the vtec engagement, and opening up that exhaust would help. The 2.25in has to be hurting you.

so i should aim for 13.0 AF and lower the Vtec to 3500?
