2.4 intake manifold
OR a new exhaust manifold
OR a new set of tires

i guess it really depends on how far u wanna go with bolt ons.. cuz u could start doing stuff internally .

i thought about the 2.4 manifold but im running lean enough already. what if i added ss sc injectors at the same time as the manifold, without tunning obviously (07). how do you think that would affect my car.

i had mine dynoed and my a/f was 18/1 and then 11/1 at redline.

yea...it would basically flood your engine . However that 2.4 manifold swap give a goodgain and if you think it may have you run too lean and you still want to go for performance...look into doing internals...maybe new cams or something

if you're running that lean... it's not because of your mods. 18/1 looks really high... was that while you were on decel?

It looks like you're ok to me. Chances are they were pretty much off the throttle at the very beginning of the log. Once they got into it the a/f evened out. You're still running pig rich from 4k on.
