What do guys call rich, lean, and safe A/F's? mine right now are 11.2 across the board. Is that on the safer side? What A/F's are pushing it?

12.0 is lean....11.2 is rich and very safe...a standard for most tuners and evo owners is 11.5-11.8 ...depending on what octane you can get your hands on.

11.5 and below is good for pump

Thats what i was thinking. i just wanted to make sure. Im going back to finish my tune next week. im curious to see how much more power we'll be able to pull out of it. im on 93oct btw

yeah you have a good amount of power left in that 30r....as long as you have a good tuner you have no worries. How much boost do you plan on running after all is said and done?

im at the bottem end of 24/high 23s psi right now. i would like to see high 24s and spike to 25. we'll see though i want to keep it safe.

probably why you're not doing the meth....sad.

Meth on top of all those mods would have a sick powerful car.

11.20 if that’s were your setup is happy sounds fine. Keep in mind no two cars are alike and wideband readings can very. Very rich can wash a motor down. Rich can cause unneeded carbon = hotspots witch can cause pre-ignition. Lean well we all know were that goes. Just let your tuner do his thing.

Btw- what do you mean 11.20 across the board. That is way to rich in the low load of peak torque areas

Meth isnt out of the question yet. im going to sit on my pump gas #'s for a bit and see how i like it. i have the meth kit sitting in my room but theres alot going on right now in my life (getting married and having a baby). so we'll see how i feel about my pump gas numbers in a month or so. and if i NEED more power ill through the kit on.

I mean the A/F's are 11.2 durring the powerband. not in the early rpms

My a/f reads 10.5 all the way across obviously to rich should get a retune huh?

Tpayne84

What more can I add to gain more hp before I retune it im talking simple mods nothing big like turbo or anything?

Tpayne84

Meth or alky + a tune would make your car an absolute horse. thats probably your next step.

Would injectors or larger throttle body do much or their not needed? Cams are not all that on the IX are they?
