+1 with the MPG. Im constantly told you can tune the 328d for more power and torque BUT it also improved MPG pretty well. I have a chip express module that goes to the fuel rail. Haven't tested the hp/tq on a dino. BUT i defiantly feel the difference and power. So far fuel improvement i haven't noticed.
Im also in GA about 2 hours from Dallas. So what does the tune do?
