Before anyone says i know there was the stuttering post when cold. But since the stage 2, 3rd, 4th, 5th gear between around 3 and 4k revs when going from cruising to foot hard down coming onto boost, almost feels like a misfire as it accelerates. Any ideas? It doesn't do it at all when accelerating through the gears, only when going from nothing in a single gear.
Sounds like there maybe a small hole or rip in your intercooler hose somehere, so when it's under boost it opens the hole/crack and makes it hesitate I had it with mine
Did yours do it any further up the rev range? It's fine when kicking its head in, only does it when going from low revs in one gear
