Alright, here's a video that gives a pretty decent idea of whats going on. First 3 clips are of the engine cold, then a quick 2nd gear pull, then 3 clips of the stutter/hesitation issue after driving it for 5 min and doing a couple pulls. But if you notice, boost doesnt come on until like 4k and power doesnt come in until 4.5 or higher, which seems way laggy to me.
