Still weighing options / choices of engine build, especially header vs "Boported" E6, T3/T4 vs EFR, (paper or plastic, right?) and the subsequent finagling required to keep my A/C system.

2.4L long rod stroker on E85, BoPort Stage 3, 2.1 cam, 3" downpipe and Stinger exhaust, PIMP, 82lb injectors.

At what level of HP would I max out the stock internal wastegate / flapper if I stick with the Boported E6 / T3/T4?
