i thought i found the problem i gapped it by mistake at .003 and not 0.30 the faze sensor i mean because im bit of a divy but made no difference. so now im guna look at the fuel pressure and try another rev counter. im running standered ford plugs gapped at 0.60 now im running a groupA coil i could probably increase the gap which would help with boost the plugs are new. yeh the dizzy has been out for a bottom end re build its timmed properly. the pointer on the aux shaft is in the middle of the half moon and the middle of the rotor arm is on the scribed mark on the dizzy body on number one with everything on tdc. all the lugs are on the bottom pulley are ok.when i took the faze sensor out the other night it sits on a magnetic plastic covering with mared lines on it but couldnt see no relavance to it. the faze sensor has to holes to screw it down one elonggated and one ordinary so it can only go in one place but with only varied gap. when i took the old one out i painted tippex arround it its vertually in mirror position. the dizzy shaft has little play if anything. got new fuel lines new pump. some say the standered ignition system isnt good enough but chap at my work his saff is on 360 bhp stg 3 chip on standered everything coil/plugs/leads/pump old wiring the lot. i really appreciate your feed back on this everey body
