I've tried searching for this but couldn't find anything on the revised non pulley tunes for 91 octane, what is the timing set at on this tune? And, is it worthwhile to run it until I get my 4# and dyno tune performed? Thanks in advance.

Thanks. I've seen that post on NLOC and it appears the new pulley tunes are safe but what about the non-pulley tunes. Do they have the same amount of timing as the pulley tune and less fuel or are they completely different? Any info on whether it's worth running until the 4lber gets put on?

 

It's all about timing and A/F. I'd wait and get the right tune.
