I got a nice data log of full throttle boost in 2nd gear today and made a chart from the data:
Interestingly, I don't even hit 8 psi in 2nd gear. I do hit 8 psi (barely) in 3rd gear. It's normal to not get as much boost in lower gears where engine speed is increasing quickly and the engine is under less load. I think this concept might possibly explain why I'm getting a bit less boost than NOLA and jeepsking: I have a bare-bones 2-door with tiny stock wheels/tires (very light, low rotational inertia of tires/wheels), which would result in less engine load and quicker increases in engine speed as compared to a heavier jeep with bigger tires.
UPDATE: I had an exhaust leak causing a small loss of boost. Details later in the thread here: http://jeeplab.com/showthread.php?13...ull=1#post3705
