hi my spec is jam ecu,sps 4 branch,ct9 hybrid,zisco screamer pipe,full catback,iriduim plugs,fmic,hks actuator etc running 1 bar!

have a problem with misfiring at 1 bar, but when i slowly accelerate it boosts fine and i looked at the boost gauge was pulling well up to .8 bar etc but when i floor it it misses and boosts but seems wrong!

since it seemed to happenen at high boost i set the actuator to .7 bar and now it pulls fine:confused:

any ideas on whats wrong? is it the leads or could it be my fuel pump?

rep will be added lads thanks in advance

you have a zisco screamer pipe?.. the one that leaks all the time, sounds like a tractor, that screamer pipe?!

i dont think that would help with the boost anyway mate cause they are a terrible job so they are....

Absolutely pointless so it is!!

plugs, leads, dizzy and rotor. when i got mine mapped at .8 it was doin exactly what your sayin. when they went higher i had to have new leads as it was worse. 1 bar i had to borrow a dizzy and rotor as mine was broke aswell. replaced leads, dizzy and rotor an it cured it 100%
