VW now has a dual Charge system in production and I’ve seen other cars around, There is a blue Scion TC running a dual Charge system here in New Orleans using a TRD supercharger kit with a turbo putting out around 500HP. I remember a Bonneville Flats car set up with a 8-71 supercharger with a twin turbo banks system running in the late 70's or early 80’s also So it can definitely be done!
Keep up the great work and please keep us informed!
Now for the injector service and the lightening of our wallets (we all seem to be dealing with this lately), I just got an answer from Chris Mills @ Deatschwerks about their injector service and I would recommend the Dynamic service from them @ 29.00 each and call it a day UNLESS you need to increase the flow of your injectors. The service includes: Pre-Testing your injectors for a before and after comparison, Fuel Pressure Calculations and Performance Calculations to define the limits of your fuel system.
They also have 550cc injectors available around $350-400. they are a Drop-in fitment and flow balanced to within 2% of the set. I’ve read several great reviews on the MB forums about them.
BTW. A flow report is included with both the injector service or a new set of injectors, so you know exactly what you have and is a great tool when tuning.

I've been using RC Engineering http://www.rceng.com/Fuel-Injector-ProCal-Service-P44C0.aspx since my Supra days and I have been happy with them for more extensive race work but for the money use Deatschwerks and with the savings buy other more pressing items.
Did I notice a performance difference? Yes and No The car feels stronger and WOT pulls really hard from 80mph till I let up plus it runs far smoother than before when tooling around town. Unfortunately I haven't had the time to get another Dyno Session. I really wanted the piece of mind knowing that I'm not going to damage the engine because of a faulty injector, I've read about a few guys that scarred the cylinder walls because of improper atomization and dumping fuel. I’ve also been around enough Nitro bikes when they grenaded because of faulty injectors / fuel systems loading up. It's also nice knowing I'll never go above 80% cycle duty no matter what.
Later on down the road!
