belt slip maybe
can belt slip be like the fuel shuting off or ignition....on...off...on ..off...starting at 9 lbs boost?.....I;m reworking my duct system and should be seeing about 12 or 13 lbs....system is straight from the p600b to the tb.....generaly the p600b has good belt wrap and doesn't slip with a new belt.......I'm using an old belt...maybe it belt slip, maybe not......weather here is 40 degrees so I don't think it detonating.......anyway you lt1 guys should know.
going for the record boost with a p600b

Is your fuel pressure changing?
If your belt is slipping it could make it load up also....
What about your fuel filter?
I agree 40 degrees knock shouldn't be too much of an issue...
Agree more likely fuel....

It's a real fast on... off.... on... off...no power inbetween but still running..........it's pulling like gang busters.....1/4 tank of gas, maybe it's sucking air?.............just wanted to know if a slipping belt would be that sudden.........I'll put some more gas in tomorrow and try again......love doing that.......the problem is speed limits, lack of time in between shifts and which gauge to watch..............god I love this car.

You may also wish to look at spark retard. Last time I saw your tuning files, you were running way too much advance, which would lead to spark knock. Depending onhow much timing and the knock perameters (i.e. decay, etc) you let the FAST system pull, you will get that "on-off" experience.
