after clearing codes from computer the boost is at 8 p.*.i now and it was at 10 p.*.i or so when i got it from nate..?? do i need to reajust something

A loss of 2psi would indicate something along the lines of belt slip. Especially in the wet winter.

Is it weather/rain related?

its dry but cold .do i need to drive it more drove it for about 5 miles and thats been it.
how do tell if belt is sliping

The first indication might be black dust on the nosedrive of the SC, unless it just started.

How'* the belt tension based on the tension marks on the tensioner assembly? Does it have a 3.5" idler, or the stock 3"?

dont no i will go see. sc pully is 2.13/16 ideler is 3.9/16 is the sc pully supost to be 2.5 or 2.1/2 thats what nate said.ok measured outside so inside should be were belt contacts ribs is 2.5 or 2.55

? can i go to a smaller pully like a 2.3 or 2.2 with what the car has done to it i puting the ceramic coated P.E.M.* on this weekend.nate got for the car and incloseing the C.A.I.

do NOT drop pulley sizes untill you have tested the Fuel Pressure

And inspected your EM'* for cracks (off the car) and scanned for KR.

ok i'll do that this weekend thanks
