Well hes already got the 24 in there and cant even get anywhere near it. So it wont matter whether he hooks it up with or without the EBCS connected. Remember the EBCS can only control boost ABOVE the wastegate base pressure, below wastegate pressure it doesnt matter how much pressure you do or dont bleed away, it wont really make a squat of difference. So straight away we know there is nothing wrong with the EBCS.
But yeah, still probs a good idea to test the lower springs first.
The only 2 options are as ive said, a faulty wastegate actuator that isnt opening at its advertised pressure. Or something weird like a massive blockage or leak in the intake or exhaust.
Need to properly test the actuator off the car. That way you are getting an acurate test of the actuator alone, without the variable of the car.
I have a mity vac.
