KR on the 3 to 4 shift after letting clutch out

[jon6.0]

Curious about what you guys do about getting KR on the shift? Shifting at 6700-6800 basically drops me back to peak torque going into 4th gear. Should I spin it higher like 7000-7200 before I shift or do something else? AFR was .73-.74 lambda and I run E85 with a 15gph methanol nozzle. What I think is a pretty darn conservative tune of 11* at 5200 and ramps back up to 14* by 6000rpm.

My knock decay rate is quicker, knock attack is at 2.00 across the board, and burst knock is off. Knock sensor sensitivities have been left stock.

Try to disable CFCO and see if it is the same or not

I just looked in my tune and it already is disabled. Thanks for the suggestion though. Enable temp is set to 300F.

when you push the clutch you are moving quickly from 13° to 45-48° even if your ho table commands a maximum of 42°.
Try to check what is adding timing in order to go to a maximum of 42° as commanded that is already an high value.

Knock attach 2 is quite low pay attention.

What is you rwhp?I would consider also 1-7/8" as a minimum.

I'll take a look when I get home. Thanks.

I already talked to Pfadt about switching to thier new 1 7/8" headers and they said it would only be worth 10-20rwhp for me. They recommended not wasting my money. I agreed with them, lol.

Current tune with 11* at 5200 and ramping to 14* up top:
