hey guys got my turbo put on, all tuned on 16.5 psi running 251rwk with all supporting mods.
the turbo does hold boost but as soon as u hit 5,000rpm it just hesitates and drops off to 5 psi. can hear a hiss but cant find it.
took my car for a drive tonight and didnt feel as strong at higher rpm.
boosted it again and it got way worse. in 3rd gear soon as i hit full boost car feels like the brakes are being applied and wont rev anymore.
the first couple of times when its just warming up is fine then it does it. boost was dropping down to 4-5 psi.
turbo is new. checked all my hoses and inspected the turbo and its perfect still.
only thing i can think of what i did last week i wasnt paying attention and i ran up a rounded gutter and cracked my front bar. been doing it since then. few days ago
