got a boost guage fitted now.
basically the car is boosting just under 1 bar say 0.8 ish
it still however missfires.
when we first put the guage in the boost wasnt even rgistering 4psi so we turned it up on the actuator.
is this te right thing to do? what can be causing my misfire????
i thoughtit might have been bent valves but it drives 100% perfect until around 4000 rpm at full throttle but will rev right up at half throttle. the boost gauge dioesnt jump around when it is mssfiring, it stays the same
