I noticed tonight when I floor my truck and see how hard of a pull I can do with it, once it hits the low to mid 20's on boost it's just like it cuts out and loses boost. Boost gauge falls to about 10 psi, smoke still rolling but not as much. It does it on different tunes, no check engine light, and nothing wrong otherwise. Runs and drives good. Mods in signature. Tonight was actually the first time in well over a year I've done a full power pull, so no idea how long this might have been doing it. Any ideas what's going on? Thanks,

Justin

do you still have the rubber elbow on your air intake? I have seen it where it gets fatigued and soft and under a hard pull, it will collapse and basically starve the engine for air.
