ok fitted my new sec's monitor, and its readin 3psi less once on boost then 3 gauges i've got. and also stops readin over 27.5psi on monitor, 30 psi on other gauges, inc autometer, racetech and a mocal boost gauges.

it's a 3 bar map, on 3 bar map settings on monitor. its running off the same vacum pipe, and no boost leaks in pipe work.

gonna try a mates brand new 3 bar map.

anyone seen this b4?
