i have a 1988 t2, i removed the air pump and junk so i only have 2 belts, power steering and alt. anyway i was driving around last night and when i hit high boost it feels like the clutch is slipping, it isnt that old maybe 20000 miles or so of less than spirited driving. im wondering if i need to get a stage 2 or something like.

i have a new ecu and bigger injectors, full exhaust including dp and no cat and a hks intake
