Hey guys I have an 88 supra turbo that bogs down when i get to around 3000 rpms. I did a boost leak test...nothing. Did diagnostics...nothing no blinking light. I dont know if it would affect the boost but it has a leak somewhere at the exhaust manifold...not sure if its a hole or the gasket could be bad. I dont know whats up with it I tried searching and found some things but didnt really relate to my prob. If you guys can help I would really appreciate it. Thank You.
