Volant Powercore Cai Problem

Stoneman2382 · August 3, 2009

Hey Guys,

I just installed a Volant PowerCore Cold Air Intake on my 09 GMC Sierra Denali. I had my truck custom tuned w/ a DiabloSport Preditor prior to installing the Volant CAI and my LTFTs were exactly how they should be. After installing the CAI and doing some logs, My LTFTs are saying i'm running 15% rich. I've checked for air leaks and made sure everything is tight mulitple times, but they are staying at anywhere from -13 to -15%.. Has anyone else run into this problem?

Here's what my CAI looks like

but here's a better look at what the filter looks like.

Does anyone know why this is running so rich? If anything I would think it would run more lean...

did you have lew tune that to match your cai or was that done afterwards?...usally you will want to re-log each time you add something. I actually re-log for winter/summer switch along with antime i feel the truck not runing as good as it should be.

well, I haven't adjusted anything for it yet... trying to narrow down the issue..

his LTFT's were perfect, at 0 to -1... then, he added that volant cai with that new style "powercore" filter of theirs.. and the ltft's went BAM! dropped to -15%...

so, by adding that CAI, it made his truck RICHER - by a LOT - which is why it's pulling out all that fuel... which doesn't make sense..

so, I have him doing a few more logs for me to log some other things so I can check some more stuff out before I go adjusting anything... cuz that's quite a jump...

may leave the slope alone, and adjust the fueling vs load tables instead... cuz one set of logs from yesterday shows that the engine load increased from adding that CAI...

odd...

Hey diablo fans. Why is it diablo lists a predator for a 99 Sliverdo but they don't list the 7.4L vortec engine option in there programers. They list the LS style engine but not the L29. Can the L29 Vortec motor be tuned. Any info appreciated.

no it can not... it uses a totally different PCM than the others... and that different PCM is not supported...
