When calculating the MPG are you using the onboard computer or is it a true calculation from the pump...just curious (averaging about 10.7 per onboard computer). Big shock to me...traded in my 2005 Chrysler 300 for this new toy...23 MPG to 10 big change.

It's the sitting and idling and the stop-n-go sh!t that eat the gas....No miles clocked to the engine run-time sucking gas.

That's why Hi-way miles are always better on mileage...Easier on mileage to maintain cruising altitude than the take-offs to get there.

Hey Dave from Down Under..here,
err Ok we've been all converted down here to ltrs / 100km for the last couple of years...so currently our 06 with about 6500kms on it cracks 18 - 20L/100 round town, but mixed with h'way she gets mid 15s/100, which i'm very pleased with as we use our truck for a lot of long weekend runs, and not much of the milk and bread town runs..

I fitted ours with 24s, and 3/5inch Deluxe drop, and corrected the speedo error [huge!!] with the Hypertech programmer, and set its fuel to 87..runs fine..didn't fiddle with limiters, shift points, firmness etc...but she still needs more grunt out of the hole..but with my latest addition the Corsa Touring exhaust it seems to definitely have more power further up the rev range definitiely..it really pulls harder at higher revs..just not off the line[..never has tho..might be due to hauling 3+ ton, I guess..]..I reckon mpg came back a bit after Corsa..but that gots more to do with me [family] enjoying that loud pedal !!..just sitting [Park] from idle and giving the throttle a stab causes it to BARK, stroke it a few times upto 5K and on the back off sounds like she's spitting rocks..enough to make you brake out in lather of enjoyment..causes people to come runnin..that Chevy engine sounds like she's ready to hit the speedway track..best $ spent so far [if you couldn't tell already] and Hey no drone ..how goods that..oh yeah mpg ...don't drown her in fuel on take off ..once launched momentum and light pedal applications works a treat...long tunnels with windows down won't help mpg but will allow aural enjoyment on kick down..

Regards
david
