yes it is.
For more help post a log and your tune and your hardware (modifications etc)
Here is all info. It seems to be an ongoing issue. Any help would be appreciated. I have Greg's first DVD on order from summit, it should be here by Monday.
Thanks.
The mods are: 2008 GMC Sierra with 221/224 114 cam, Front mount Turbonetics 76 ball bearing turbo, Snow meth kit, 5-6 psi at the moment.
try decresing your MAF Freq table from 7000 below my 10%. take another log and change according.. or subtract 10% from your Offset VS igniton voltage and post up a new log. the MAF Freq is probably easier for you.
your AFr at WOT still looks a little rich..
