hello all. I've been chasing an issue for a while. The issue is intermittent, happens more often in lower gears. I will have a slight stutter or no stutter at all WOT up until around 7k rpm it'll backfire like it hit limiter and then proceed to misfire for a few seconds and eventually it'll settle and the car can be driven normally again. I have changed the following, fuel filter, head with new valve springs (thought old ones were bad), new turbo, new bov, new coil pack, new wires (ngk), new plugs gapped around .018 (pump e85), Power transistor unit, new alternator, manual boost controller. I haven't swapped ecus but i have taken a look at it and no visible damage. I have provided logs, this happens regardless of boost level. Mod list is accurate, running speed density. Mechanical timing is good.
