...losing boost? I have a 99 Buick Regal GS Supercharged and a couple months ago when I got the car, it would boost around 7-8 psi, and now little by little it has gone down to where it only boosts to 4 psi. The supercharger isn't leaking or anything, it sounds fine, and boosts instantly just like before with no problems at all, but it only goes up to 3-4 psi now instead of 7-8 psi like before. No check engine lights, No other problems at all, just a big difference in boost now. Anyone else had this problem or know what it could be?
The belt does NOT slip at all, everything is stock and the car has no add-ons. Everything is stock and nothing has been changed about the car since I got it(coupe months ago) but the engine oil and tires. Thats all.
