I scanned the car on my way home Friday and with the stock thresholds set for DFCO, the car does not enter DFCO at all. The MAP values seem to be a bit too high to meet the entrance criteria. MAP is...
Thanks for the input. I put the PE TPS and DFCO values back to stock along with all of the idle airflow parameters with the exception of RAF and Throttle Cracker and Follower. I drove it to work...
I don't doubt that first statement :). I've been tweaking on this thing with HPT for over 10 years now. Through two motors, four cams, multiple transmissions, etc. At this point it runs pretty damn...
I have yes.
I disabled DFCO frequently while dialing in the MAF and VE tables. With DFCO completely disabled, it hangs the same way, but does not have that initial dip in RPM down to idle speed...
I find myself wanting to say something like "Hi, long time listener, first time caller" LOL - I've generally been able to figure out any and all issues on the car by reading and testing rather than...
Add me to the list 2009 G8 GT.
Glad you figured it out....and that is good information for the people that have custom fuel systems setup.
Not sure if it's related as it the issue described is usually above 11500Hz....but still worth a read.

Sounds like you may need to do a CASE learn. Otherwise known as a Crankshaft Variation Learn Procedure.
I know several GTO owners that have needed this done either after a new motor, or after a...
I took a look at my OL EQ Ratio and leaned it out for the MAP readings I see at idle. Mine was doing something similar and it was commanding a really rich AFR on startup. Once I commanded a leaner...
That pop and no start, then running fine sounds like a Cam position sensor issue.
You do need to change the engine size on the general tab from 5.7L to 6.0L. That will automatically adjust your...
Just a couple of quick ones I've dealt with lately.
Issue 1 - LS2 402 - Flashing CEL. Multiple misfires on 4 and 7. Tested wires, plugs, coils, compression, etc. No joy.
Fix - CKP Variation...
