hi every one, ive recently got an erst cabriolet, its got chip, unsure on make 4 inch stainless, filter, piper cam, the boost peeks at 20 psi and then holds at 16psi, at first when i got the car this was'nt a problem, but now it is, if you floor the car low down in second and continue through all the gears its fine, but if say your in 3rd gear at around 30 mph and you floor it , it will come on boost then just over boost and cut,
is this just a case of adjusting the actuator, thanks
