boosting issue? PLEASE help. any idea is helpful
So i was having an exhaust leak 2 weeks back, finally figured it out with help of some people on the forums, turn around before that and still i'm having a boosting issue. Currently running a Tomei 7960, which should have really quick spool up time. The issue is i'll start building boost at 3,000rpms and it will drag out till 7,000rpms and will boost SMOOTH from 0psi to 18psi-20psi. Exhaust has a hollow sound as if the car doesn't want to build boost. I've been having wastegate issues either not opening and spiking really high or not enough in this case, or not fast enough. The WGA arm that goes over the wg flapper arm pin wasn't going on easily(picture1). Well i kept having to turn the wga arm with a wrench to a certain spot then tighten down the nut to get it to go on smoothly(line up). I' tested the wga with a compressor and it works smoothly NOW, wont bind up anymore like before(opens flapper 1\4 to 1\2 way and will get slightly stuck then open more or make a screech noise as metal on metal). I've boost leak tested, fixed all the leaks besides Throttle body shaft seals(they are in the mail atm). but wouldn't cause a HUGE problem as this. I had stock turbo in boosting 21psi and was doing perfect, with mabey a 3psi drop. thanks for ANY ideas.

Did you loosen and backout the back-up nut before rotating the turnbuckle on the end of the actuator rod previous to trying to get the arm back onto the flapper valve pin?

I'd like to know how many threads are visible and exposed beyond the turnbuckle on the end of the actuator rod as you have it adjusted in the image. It's not visible from the angle of your pic.
