do you have a boost guage? what sort of psi are you getting, if the stock ecu sees too much boost then it will automatically retard the ignition and back off the boost so the bleed valve could well be the prob,
no i dont have a boost gauge, so im not sure what pressure its running. the bleed valve has got 3 sections where you can connect pipes on too, two at either end and one at the bottom, the one at the bottom hasnt got anything connected, could this b a reason?
possibly, but that sounds like the third connection is just where the air is bled too from the actuator line, i'd be looking at getting a boost guage, and an air fuel guage, see what the car is doing, bleed valves kill engines if not set up with the proper ignition/fuel mods to match
