This makes me sad hope you fix her taggy, you need to get the money's worth out of what you put in, you'll just have to put in a bit more! It's simply an unfortunate circumstance, there's noone to blame essentially, it could be a fault that occurred well after mapping/engine build, it's likely that its just coincidence that it happened a few weeks after, if something was wrong during the time of mapping, no doubt TD would have noticed. Anyone with half a brain cell that maps cars would know if it was running lean enough to cause this amount of damage, surely.
