I don't know how so many members can run a 3.4 and not see any KR with just rockers or a cam and no I/C? Granted I have a GenV.

My mods are L32 GenV, XP cam, PLX WB, TOGs, FWI, 2.5" catback exhaust.
-------------------------------------------------------------------------------------------------

These are scans on identical road within hours, the only difference in both scans was the pulley size and reduced timing for the 3.4 as a caution. AFR Wideband shows a 11.6 AFR for both WOT runs.

3.4 scan; 15* of WOT timing and 4* of KR



3.6 scan; 19* of WOT timing and 1* of KR.



I have a Racetronix pump and wiring harness with 63# injectors. But if the wideband says 11.6, that means there's adequate pressure assuming enough fuel is being added, or not?

Lastly, the average boost in the 3.4 and 3.6 scans are 10.1 and 8.3, respectively. I'm just dumbfounded that an extra 2psi with the 3.4 can be so limiting to the amount of timing?

Wow that is odd, your scan seems spot on. Have you tried richening it up a tad more and then adding more timing? I see you are already a tad rich though. Did I just miss seing it, what is your MAF looking like in hrtz? It would almost seem your MAF is maxed out a bit.

Thanks for your input. The highest MAF reading with the 3.4 is 10,610 Hz and I believe the ceiling is 11,500 Hz, I just don't know what's up.
