afr?

[general01]

lookin for you guys oppinion on a safe afr for a low boost street bike tune. the bike has a pc3 usd and the ignition module and is also running a full set of seconaries that are boost actuated. i was also planning on pulling a few degrees progressively from 5000rpm up to redline(in the boost range) prolly up to 8 or 9 degrees retarded at redline. what do you all think? thanks

11.8 is a good target afr on boost. 12.5 off boost, (street cruising).

No need to pull timing below 10#. If you're running more boost than that, shouldn't need to pull more than 6 degrees @ 20#.

Anything more than 15# needs race gas (C-16) IMO.

Hmmm, if you're not sure about it, might oughta get something to log EGT.

I thought you were on a busa, sorry... I just assumed that.
