supercharging a steptronic 330xi
A search yields little about what I am about to ask:
What sort of hidden costs (anything additional to the actual cost of the supercharger) can I expect?
I'm looking at ESS's supercharger to add some power to my 330xi.
Either I supercharge it or fiddle with the exterior. I prefer performance, but if there are too many hidden costs, I will most likely be swayed (bar lol) towards a vorsteiner CF vented hood + m3 bumper + CF lip.
I want to make a decision by Monday so I can get on with my life!!!
Oh, I have ~65k miles and just finished Inspection II. Additionally, I have 19" m6 reps, smoked everything, K&N intake, magnaflow exhaust, eibach springs.
