Supercharged 2007 328i
Finally had some time to do the supercharger install on my 328i. This is the Gen 2 kit with new injectors. There have been some minor idle fluctuation issues but they seem to be getting better. I installed new NGK copper plugs one step colder than OEM gapped to .030. AJ at ESS is telling me it may take a few days for the idle adaptives to learn, so i'm going to give it some time. I went and put a hundred miles on it after work so that I could try to get the adaptives to learn a little quicker. After having done that I did a couple of WOT pulls with the traction control off and spun the tires all the way through first gear. A new feeling in a 328 for sure. it's definitely making some boost. haha. I'll need new rear tires soon. It currently has the 120mm pulley installed but if the tune works itself out, I'll switch over to the 115mm pulley for more powa!

This is really awesome, I love enthusiast projects! Hell, if I had saved all the money I spent on my car and my mods I could have a much nicer car too, nice build!
