Hey guys I tuned my truck with a tune that was pulled from various other tunes and came up with something that works better than what I had, but still getting me tons of KR. I have a 2000 Silverado with a Whipple at about 5-6psi and a 6.0L. I am attaching my EFI log, and wondering if anyone can help me with this. I think I am running out of fuel based on my LT's, but maybe someone can point me in the right direction. Thanks.

wideband would be more accurate. also if your getting knock retard or possibly audible knock you need to get off the throttle .im also guessing your running a non intercooled whipple so iats are also probably up there not helping . do you have any logs?

I attached my current log on the first post. It is with EFI Live. IATs when knock occurs is around 144 F. Yes, it is non-intercooled.

Where do you have your fuel enrichment set out? Post up your tune.

You need to log your GM.INJ1PW and this CALC.INJ1DC to see if the injector max out. I would get wide band to see where AFR is. You should be going into fuel enrichment some where after 95kpa.

I have an OS that doesn't support either of those PIDs. I wish I had the Duty Cycle one, that would really help.

IF was me i would move up to a cos3 to get boost settings. I would up grade your injects to of min. 8.1 for 6lb. Your b3605 way to lean after 90kpa.
