2003 Dodge RKL Puff Tune

[5point9]

Alright.. decided to mess around with the puff tunes. I love my predator, and almost always run the extreme tune with the extreme puck as an added bonus.
Keep in mind, I have some supporting mods.. walbro fuel system ,exhaust, intake, gages. I DO have a low pressure fuel gage, and when describing the problem below, fuel pressure was GOOD! It did not drop below 16psi.
Loaded the RKL puff tune, no stack. Did shut of the puck, turned it down to 0 percent.
As I started to roll on the throttle, as soon as the boost began to build (5psi or so), the truck bucked hard and temporarily shut down. Sounded and felt awful.
Anybody else experience this? I was worried about trying it again and just reloaded the extreme tune. No problem with that tune!
Mikel?
