So my story tonight is ... I was on a 25 mile highway trip to a customer and I was surprised how the R was able to boost quickly 2-3k and 8psi in less than a second. I got off the highway and the butt dyno said right away something is slow. I was able to boost up to 5psi under full acceleration. I made it to the customer and the car sat for 2 hrs( checked under the hood and no bad smell, didnt hear vac leaks, everything normal). On the way home I was still getting 5 psi boost. When I got on the highway in 3rd i pushed it to 70mph and got 10psi. As I got closer to home I stopped getting any boost and 3 miles from home it was really hard to go over 3.5 - 4 rpms and no boost at all. When you press the gas there is no misfire( runs smooth) but feels like its getting hell of a workout to accelerate or raise RPMs.<p>TCV or its gonna get deep in my pocket?
