Alky Tunning.

I was out tonight tunning with the alky from SMC, I am running a 18*timing chip, being conservative for tunning, anyway, finally got it to 21psi 0 Knock, at wot on third doing about 110, with a pump speed of 9, but my 02's are on the rich side about 834, should I lower fuel pressure a couple of pounds, or just put in the 22* timing chip to make it run lower on the 02's, what do you all think?? the car feels great and it runs like a champ, but I think lower 02's will make it feel even better...

imputs welcome.

Crappy California 91 pump gas sucksssss :mad: thank you SMC..
 
I'd pop in the 22* timing chip if it's the same type as the 18* one.

Set the boost back to 19 psi. and work back up tuning for 0 KR.

Be wary of transitional and part throttle KR from the higher timing chip.

Good luck.
