Green diesel ecu reprogram

Ready to pull the trigger on the Green Diesel mod for my 07 GL320. Is anyone running this mod on a early GL?

I'm interested in that myself. It looks good to me...almost too good to be true. Where do they get 15% more HP, 10% more torque, 15% better fuel economy, and less turbo lag? What are you giving up to get this?

And the comment about turbo lag has me wondering as well...I've bypassed the swirl flap motor on mine. How does that affect things?

Computer tuning without concern for emissions.

Rail pressure, injection timing, pulse count, pilot quantity, no EGR, close VNT vanes further, reduced DPF regneration.

There's a 4-pin connector that plugs into it. The bypass is to pull that connector and put a 4.7K resistor between the center two pins (one end may be unused, but it's pins 2 and 3). I stuck the resistor in mine and wrapped it up in self-vulcanizing rubber electrical tape to keep it from coming out after getting the dreaded P2015 check engine code. Cleared it, runs fine.
