i think this tune is perfect. dyno guy said its too lean. what do ya'll think. i normally like this kinda tune on a forged piston though, i forgot that they werent.

If it were mine I wouldn't run on the spray that lean. You can lean it slightly after your torque starts falling off, imo, that's how I have mine. 11.5 then 11.7/11.8.

13 is fine anything leaner than a 13 you will have some problems. Spray would be same at 12 or so.

You can run 13 on your set-up, but to give advice that 13 on the spray is ok is a little miss leading, imo.

No doubt. I'm going to agree with Robert on this 1. Your tune is to lean, I'd go 11.0 to 11.5:1 on the hose. You run a 13:1 on the bottle and something is going to melt.

Making that kind of power I would shoot for at least 12:1. More like 11.5:1 would be ideal like stated above.

I had a A/F graph like that before but the car ran fine. I think I may have had a small exhaust leak or something though.

Oh sorry about that, it was my falt for not reading the dyno sheet close. I did'nt even see the 100 shot run on there. yea, 13 is going to be too lean for you bud. 11 or so will be the savest bet. Sorry for the misleading it was my falt for not read the whole thing.

Forget the dynojet wideband. That thing sucks.

Pull the plugs. It's the ONLY to way to be 100% sure.

It's a good tune in a perfect world, but unfortunately we don't live in a perfect world. One bit of bad gas or a fuel supply hiccup and you're done. I run mine in the low 12:1 area and consider that pretty hairy. Good luck!

so theoretically, if i just change the 22 fuel to a 23 should be safe enough? or would you goto a 24? also, im wondering if a/f is gonna be the same going up in the jets, like if i goto a 200 shot, is it going to have the same a/f? So will i have to up the fuel jets in the bigger tune up also?

If you change jets especially with a big shot it's always best to do a dyno pull to see where the A/F actually is.
