My Daytona had been running good and boosting like it should. Then I hit a few issues. It wasn't boosting before, found out it was a combination of a stuck wastegate arm and a blown coupler. I could run with a Turbo Grand Am and was hitting 14psi fairly early in the rpm range. Now though, I don't even see any boost until about 3k and not fully spooled until 4500ish. I can also smell gas when driving, its like that smell you get when running premium. I've checked timing over and over, also had a local guy come over and set it for me. I can hear the turbo spinning but it just doesn't make any boost. I've also looked over the pipes for blown/loose couplers, didn't find any.
