Well my car has been sittin all winter and I finally got it out today to take it for a drive. I did a few 3rd and 4th gear pulls and the car felt ok but as I was watching the boost gauge I noticed a few times it was'nt showing any boost and then when it did show boost it was only showing a few pounds. Any ideas??

if you think it was running like it did before you parked it, maybe your guage is bad.

check your vacumn line for your boost gauge maybe its dryrotted or something

If the car felt 'OK', then I am guessing it is the boost gauge. If the car was not making boost, you would notice it.

what turbo kit do you have ? you might have a cracked exhaust manifold.

the only thing i can thing of is to check the piping from the compressor and the throttle body to see if you have a leak anywhere, also how is the belt for the sc looking ? . if the car feels strong it is probably just a boost gauge problem.

I agree. Do a boost leak check by capping off the inlet and hooking up some air to it. When logging my car, I noticed it was down about 4psi. I performed the test and found that my bypass valve was stuck open ever so slightly.
