Anytime you increase exhaust flow (cam, LT's), you will likely loose boost as the measured boost is a measure of resistance. You will be making more power, but showing less boost on your gauge.

ive read several people on here saying how they lost boost with a cam, and a couple of them had " boost friendly cams" 114-115 lsa, yes mine is a 108 lsa, and i understand you loose boost with a cam and longtubes, so will the gauge just read lower, or am i actually loosing the boost. thanks
