I will take pictures of the back of my series 1 tree. Did you check your gasket below the supercharger that seals it to the top of the intake manifold? Mine is worn and cracking and now extra air is being sucked into the intake, after the MAF, causing bank 1 to run lean and a check engine code. The miss between 2100-3000 sounds like it could be a spark plug issue, or a coil plug not giving the spark plug spark, causing it to miss. Are your plugs and coil plugs original?
