Have a pretty stock BA xr6t, has xr8 pod style filter, hi flow cat and 2 1/2 inch exhaust. I bought a flash tuner with a 11 psi tune on it. Is this too much boost for stock internals? If so could I just regulate the boost down to say 8-9psi with a boost controller? If not what PSI should I ask for in a custom tune? Thanks for the help! Chris H.
