I'm not concerned of the hp nor the torque at the moment. This dyno was done because I wanted a pre and post of a custom true dual exhaust setup I'm having done at a local shop called Eastside Muffler. Anyhow, what do you guys think my afr? I'm hoping to do a ecu flash after the the exhaust is put in.

running a bit lean in the beginning but it drops down. Typically a safe setup would be 14.9 at idle or no load and at WOT you want 12.9-13.3 across the board until 5500 rpm and you want it to drop down a teeny bit.

how much gain do you think I can make from a tune with how it looks now?

Im not sure, EVERY car is different. After I got a tune I didnt gain much topend but the midrange gained a fat amount of hp/tq. Honestly, you never know how much your gonna get. You might get alot you might get a little it all depends on your car. Your not running too lean but you should still get a tune. My car was much worse than yours.. My afr was spiking up to 15.5 - 16.0 before tune. Trust me its worth it get the tune.

your power willl be made from advancing your timing. you will just need to compensate your AFR to match the new timing.

we cant guess how much more power. depends how your car reacts to timing changes.

Looks to me like there is some power to be made in fuel tuning too. Pig rich from 5k up. I agree that timing looks to be more critical, but def some power in a refined (13.0 WOT) fuel curve.

Thank you guys for the response and advice. Appreciate it alot. I'm pretty psyche. We'll see what the exhaust will do to the overall gains. Oh, eventhough jo from eastside muffler disconnected the battery during the install of the headers and test pipes I didn't reset my ecu manually. Well, I got the chance yesterday which I also did the accelaration relearn and throttle position, idle, etc... Man, I can now feel a difference. I wish I could of did that before the dyno.

My 07 AFR spiked at 22.1 on the dyno base run today.

Was that dyno done with all the mods currently listed in your sig?

Nice. Mine made 240whp & 226wtq on the same type of dyno. I was curious to see if my #'s were in line with other people with similar mods. It seems so.

I always thought that dynopacks read within 1-2% of dynojets? The only dynopack I see with any regularity on here is church which seems to read crazy high.

That AFR looks very close to my stock 03 G35C.

I would say if you stabilize your AFR you will see nice gains and on top of that if you get a tune you will see further improvements.
