my m90 use to boost about 14 and a half lbs at the top of 4th gear, but now it only gets up to 11. 12 on a good day. and in 1st gear when i jump on it it would jump to 10 lbs and now 8. could this be from a belt slip? i moved to a town that is alot hotter the the town i use to live in. could the heat have anything to do with a belt slip? plus my rad has a leak in it as shooting coolent on to the belts. when the car is cold the belts make nosie until the car worms up. do you guys think its the belt?
thanks.:confused:
 
Most likely temperature effects from warmer outside air effects. But it would be nice if you fixed the coolant leak and replaced your belts too.
 
Yeah, I'm going to fix the leak and change the belt. I hope that works. I am also thinking of a front mount innercooler as well. Take will bring down my intake temp. But having my coolent spill all over my belts isn't doing me any good. Lol. That can ruin the belts right?

Altitude will also affect boost, I think it's around 1 psi for every 2000 ft.
