quick overboost, spike question.
the quick low down,
greddy 18G with ATP 14psi actuator, hondata PWM boost by gear, s300.
i'm supposed to make 21psi from 3rd - 5th gears.
why on god's green earth will this setup keep spiking? I've set the boost by gear to as low as 16psi in 3rd and 4th and still I keep hitting my boost cut which is 22psi. I won't lie, the vacuum from the actuator to the PWM has a pretty decent kink in it..could something this stupid cause this? if not....thoughts and suggestions please.

I've had issues controlling my boost since I first put the setup together, on the day of my tune my actuator wasn't positioned right i wasn't making my 21psi til really late in the RPM's..since i was unhappy with that, i probed around figured that out and fixed it. Now this stupid *** spike issue is the problem. I just want to make my 350 or so WHP when i'm supposed to and have it hold already..Jesus H. Christ.
