I floor it from 4th gear and 5th gear above 4k rpm and sometimes the rpm gauge bounces and the car seems like it is holding back power like it doesn't want to go harder. The Dealer said to reinstall the factory intake system and bring it back in and then they would test it, but they said since the k&n cold air intake is not connected directly to the blow off valve that this could potentially be the issue but they have no idea. I took the mechanic for a drive and he stated it seemed like a normal hyundai turbo function.
The car has a map sensor, venting to atmosphere will not harm it.
My guess is that the stock boost control solenoid is acting up. Very common that they fail in high temps. I would start there.
