Not sure on the VF chargers. They were different kits for VR6 only. They did have an exchange/upgrade program with the old Z-Engineering kits at one point though. The VF units had an oil return line and not self-contained. The Z-Engineering kits did come with a GIAC chip. I'm pretty sure the VF kits used GIAC too and had two different tunes for stage 1 and 2. Really you should be able to get anyone to do a tune. One of my kits had a GIAC and the other a United Motorsports with 30# injectors.
I'm just worried because my GTI is well over 11.5:1 compression. I'm not sure if the Supercharger will work properly or safely. But the guy only wants 800 bucks, so I'm buying it anyway.
I vote keep the GTI all motor and put the charger on another project!
Yeah I've come to the conclusion that there's too much compression.
If I do another project, it'll be a cheap Jetta DD, since I want to keep my GLI's miles down, and keep my GT's paint fresh as long as I can.
I managed to find a low mile memory red car and I may end up purchasing it, even if it's expensive and automatic.. But I have to go to North Carolina to pick it up. ;O
