hello,could someone tell me what bar boost i should be running with a stage one chip.at the moment if i accelerate quite hard in 3rd gear[it happens in other gears as well]with the revs low as the revs rise and the boost tries to come in the car backfires and pops and doesnt accelerate,it pops and spluters for a bit and then clears and the boost cuts in,could this be too much boost?i think its set at about 1.5 bar.
thanx.
