not sure about running high boost above 10,000 but running at high boost at 5300' no probs thus far and there is not other dyno/tweaks required. That is it.
Side note: I took it to a dealer yesterday for a rattling noise and they had to test drive it. They could tell there were some changes since they mentioned the fact the intake could 'void the warranty' due to the oil? true? I think when they see the BMS cones they put 2 and 2 together and determined there is a piggyback as well. He did ask about other mods but I didn't say anything. I don't think the dealer mechanics are that dumb but luckily they were cool about it.
The rattle was a loose driveshaft?? not sure how the hell that happened. maybe too much power
