Hey, I was reading the performance section of the TDI club discussion page and found several threads regarding the use of propane fumigation. Apparently the addition of propane to the intake allows the fuel to burn more completely, thus yields better economy, power, and engine longevity as well as cleaner oil. Has anyone here considered this mod.?
Anyhow, here is a site that actually sells a propane kit: http://www.bullydog.com/
Bully Dog boasts of power and torque increase of up to 66% and fuel economy increase of up to %40.
I'm intrigued!
