Any chance your belt is slipping from the start some, then getting worse and just letting go? Reason I ask is I have seen that happen in my friends supercharged Mustangs.
Still fairly new to Lightnings myself, but figure it's worth taking a look into. Just look at the belt for unusual wear marks.

Tried 2 chips and the stock program - no difference
unpluged boost bypass - no difference
and no belt slippage
The truck launches great and runs good to about 4500 rpm in each gear then it dumps the boost from 13#s to 0#s

yep - it still does it
did the same thing on I did my Lightning but didntwork on this. I tried unhooking and plugging the lines off the acuator that operates the bypass valve and still no difference starting to wonder if this truck has anouther dump valve somewhere
Thanks for the tip but so far no difference
