I think you're seeing belt slippage, what does the dyno graph look like? A new blower belt will often appear to be too small to fit on the blower, but after a half an hour to an hour of use the belt will stretch out. During this break in time the engine should be kept from going wide open throttle, until the belt is tightened back down after it stretches. Once a blower belt slips it is more prone to slippage. You might also check to see if the air filter is too restrictive, by taking it off and making one run to see if you see more boost. If you do see more boost, then either the filter is too small or it needs cleaned. Bob

Belt slip issues with the truck kits are a result of only using a 6-rib belt and using the weak factory belt tensioner. I have a solution for both of these problems, if your interested send me a pm.
Regarding the 600 rwhp goal, it would benefit you to step up to the D1sc in my opinion. I would think you'd have to spin the hell out of that p1 to see those power levels. IAT's would be lower at that power level with the D1 as well as you would not have to spin it to the moon.
