Message	i run very rich due to a canned tune and am running stock cats. i am bypassed the manual boost controller thinking that had gone bad, so the wastegates should be opening at 14 psi (what i adjusted them to). the car revs fine, pulls fine, but hits a wall at 7 psi and shudders. do you think the stock cats may be the cause. fuel pressure is fine. blazt diagnostic shows normal life and function with timing, maf, voltage, etc. thanks. p.s. i dont have time to search right more now and diagnose because i have important work stuff coming, thanks for the help.
