upgrade to 16g now boost creep at 4500 any ideas y???

it's creeping to full turbo boost then fuel cutting it's like the waste gate is just shutting at 4500 rpm any body have this problem i think the waste gate acutuator is broken but not sure stock boost control is hooked up still not a mbc

what kinda exhaust do you have? is the WG flapper on the 16g stock?

Did you port out the wastegate hole and put a TRE 34mm valve on it, I believe this is a must do. www.teamrip.com

no i didn't do the ported wastegate and it's still the stock 16g waste gate i have a 3 inch apexi dp and 3 inch greddy evo exhaust with no cat also it only over boost at full or 3/4 full throttle if i watch my boost gauge i can go to 7000 rpm with no full cut and no overboost but if i push the peddle to hard it overboosts
