Fp red car acting weird.
You must live in SoCal, huh? If you lived in the Bay Area then you wouldn't have this problem. Take the 4-hour drive(@ 80 mph)on up to Hayward, California and have Bryan @ GST set your tune.

OK now the problem, when im driving and i hit under 5psi its perfect if i try to hit it a little bit more like 10-15 psi car will stuttered like if my bov or my wastegate would try to open, my needle on the boost gauge will bounce a little bit , but if I hit it to WOT , the car is fine and will take the whole 26psi with no problem.
At first james (at reese tuning) told my its my bov and to adjust a little bit more but it still doing the same, what I can think is that my wastegate acutuator, becasue im running the stock and not the silver one from FP, since i bought the FP red from a guy selling it at socalevo, it came brand new plastic wrap and everything. but the actuator was the stock one
could that be my problem?

The Greddy Bov's are not crap initially, however, when their rubber diaphragms wear out, the units are useless. Take your bov apart and I can almost guarantee that your have a tear in your diaphragm(this would not be the case if it's less than 3months old)
On the flip side, the Tial acting in the exact same fashion as the Greddy should not be an identical feel. Maybe a little tuning related or hardware. Who knows?...
Take the advice of the other people and find someone local with a JDM metal bov and see if it still shudders.
Last thing. "it came brand new plastic wrap and everything. but the actuator was the stock one"
The FP wastegate looks stock but it's not. To know for sure inspect the locknut on the wastegate arm, it should be a 13mm vs the smaller stock nut that's a 10mm
