Figured I'd update. My last fill up I had 59.08mpg, my TorquePro app on the phone says I'm at 60.7 this tank. I'll have solid numbers Monday morning.
2000 VW Jetta, KermaTDI tune, VNT17, SouthBend Daily clutch, .622 5th gear from Cascade Germany, coroplast grill block, FIY cranck case breather, 205r65/15 fuel fighter tires.
