Just curious if there i any "risk" throwing a couple degrees in my car at the track. Rough breakdown of my set-up:

370ci 9.1:1cr
T4ST80 at ~11psi
dual nozzle alky control kit running pure meth
91 octane with a gallon or two of 110 mixed in a full tank
17* built into the tune

I have efi live and can add a couple degrees if I want. Ambient temps should be in the 75--85* range or cooler.

Whatcha think? I figured I'd be okay throwing a couple more in it if I need to shave a few hundreths

looking for 9's huh.... Are you talking 2 degrees or more? Can you not just up the boost to try that instead?

Give it an initial baseline run at the track on 17* and check the knock tables. If they look good (ie no knock) with a stable AFR (11.xx), then you can try a couple degrees. If it begins recording knock, get off the gas and bring it back to the previous 17*.

As a side point, I ran a fat 11.1 AFR on my STS, but bumped the timing to 20* safely. It was only 5PSI, but the principle is the same.

Good luck on the 9's. At least it's not raining where you are.....like here

I am LOW 11.XX AFR too. I talked to my tuner and he said just go 1* at a time and I should be fine with 20. Can't up the boost because the tune is locked.

I think you should be OK with the good fuel and meth.

Best of luck... got get them 9's

what do you mean the tune is locked, are you saying that the tuner locked the PCM.

How are you able to add timing but not boost if the tune is locked????

I run 12 psi with a fat afr. low 11 high 10 . and 20 deg. timing and strait meth. Going from 18 - 20 gave me 25 hp or so.

Im also stock motor

EFI live can add timing while it is running, but can not permanatly alter a locked tune.
