I would pull 2 - 4 degrees from 3750 to 4500 rpm too but it will take some work to regain the power but it will be consistant, believe me I had 9's there too.

First and foremost, either spray the methanol earlier or add about 2points fuel down to like 90% load, You put an intake on there or something

I have and was tuned for a ARC intake.

the only reason you would pull timing out is to lessen knock and he doesn't have any so that doesn't make any sense.

just add fuel to get the AFR in the 12's during spoolup and out of the 13's If it still isn't knocking you might be able to add timing to increase the torque off boost.

what is everyone running for afr in the 3-4k rpm if you don't mind sharing. What is the concensus for a safe afr during spool up.

Title of his log is "good pull".

One account of no knock is not a good way to determine if timing is too advanced and several degrees beyond available power gains, unless your limited on time, resources, and knowledge.

Believe me, 4 degrees at peak can feel just as good as 10* at peak without knock. It just takes more work to get there - Bubba

hahah, funny you noticed the "good pull" title. I have had a recent problem of blowing the intercooler pipe off the i.m. while logging. The "good" does not reference the tune, it references the log, it's good "data".
