Ok. I research on this forum constantly. Here's my deal. I go WOT from dead stop or rolling and i see maybe 2lbs through first then it gains a tad into second then about half way through 2nd it jumps to 9 or 10lbs. I know about belt slippage but isn't that more of a high RPM thing. Once it gets up to 9 or 10lbs it stays there as long as I'm in it. I thought maybe the boost actuator wasn't adjusted right so I followed the advice on here for adjustment and when I loosened the bolts it kind of sprang up about 1/4 inch then I set the lever barely on the stob and tightened her back down. No change. Truck has 30,000 all stock(swiss cheese airbox mod) and I changed the belt at 20,000 gates green. Belt doesn't seem real snug but you can't squeeze it together above the idlers. A slight dusting on the underside of the blower snout. I never hear any squealing or such noise. Is there something I've not found yet that could be causing this lack of boost? Is it feasible to think maybe the gauge is hosed or the line to it maybe? Any suggestions here are greatly appreciated. Thanks.
