ZZ4 MPG Challenge
1500 miles or bust!! My truck will be my daily driver for the next two weeks. I leave Austin on Thursday morning for a short vacation. I'm parking the Jimmy during my trip. The ECM is being sent to www.wait4meperformance.com for reprogramming.
The challenge: estimate the average MPG for my trip. Most of the trip will be at 70 MPH. Cruise RPM 1900-2000. The average MPG in city driving is 13.5 to 14. Equal to the old stock 305!! Milage goes down a little due to dead stop traffic. |
