Does anyone have any input good or bad about these two companies supercharger setups? They both use vortec SC but VF engineering says they prefer 6 PSI without an aftercooler and will bump it up to 8.5-9.0 in march when there aftercooler kit is done. RMS kit is already at 8.5 without aftercooler. RMS lists HP numbers just at VF's. GIAC does alot of programming with my former VW so I know their work. Not sure on RMS custom software but they sound good. I've got an 02 Z3 3.0i 5speed with 25000 miles on it.

RMS's software has had a bad wrap for a while. They had a few problems and were "labeled". The software that they are currently putting out is good though. My car is currently in the shop getting the stage II RMS setup installed.:D

let me know how the setup goes. I'm very interested but seem to be leaning to the VF s/c because as say, such bad feedback with their previous software. What made you go this route since you obviously heard some bad raps as well?

I chose the kit I bought because I got an AWESOME deal.
