Dean, are you brewing your own biodiesel, part of a co-op, or buying it?
Pretty fun to start playing with diesel performance once the fuel is free. I installed a set of GTD injectors, advanced the IP timing, increased the fuelling and upped the boost on the turbocharger on my 1.9... pretty impressive change but not anything like your 240ft/lbs of torque!
Mistake I made was not running an EGT guage... Burned the turbine wheel up on the way back from Montreal last week.
Ah well, good opportuninty to upgrade to a k24 turbo.
