I recently bought a 2001 Lightning that, as far as I can tell, has no mods yet (original pulleys, no boost bypass, no intake, and no chip on the computer). When I'm accelerating at approximately 4500-5000 rpm my boost gauge jumps to well above 10# on the stock gauge. Is this normal?
Bottom is just under 8" (7.9") an the top is 3.25". Also, how can you tell if the "factory seal" has been broken on the computer. I looked at it, and it doesn't look like it has ever been messed with, but then again I don't know really what to look for.
