Haven't driven it/raced it with the new intake. Before it was done by 7000. Have see others winding it out to 7500+ on different boards.
No problems with mine up to 7500 (you can't tell from the printout but it was good to go).
Did you get a BOSS intake specific tune? They sent me a new tune when all I changed was the intake (after I already had a JLT CAI and BBR tune).
Have you called and talked to BBR? They'll fix that for you.
