Well I couldn't afford the best one, but then you can't sell Dinan kits on your site anyway.
Think about VF Engineering for the E39 and a number of other models; also consider Active Autowerke, although their reputation isn't quite as stellar as VF. I am highly intrigued by the twin screw s/c setups from Active, and kinda wish I had kept my M3 so I could slap one on...
Also note that VF Engineering is known for teh fastest turnaround time on new kits and chips, as well as teh least problems post mods (like check engone lights coming onn etc). My shop switched to VF from AA after having many of these issues. I will pick their brains as to some turbos and get back to you in this space.
