I am going to see if we can program out 8 thru 10 so it doesnt use those gears. I drive 100% manual mode so I never see anything higher than 7th at about 85 mph.
What is the gas mileage? I am averaging about 10.2 MPG in 800 miles. have changed the oil twice
You can program 8-10 out if you click the left paddle a few times in regular mode.
Also, if you averaged that poorly I'm assuming you're manual shift, revving it around 4-6k rpm and mostly WOT the entire time you've been breaking in the engine? My truck is getting 15.5 mpg the first hundred miles during break-in.
FWIW, this truck already makes like 370rwhp and 420 rwtq so it's not far off your last supercharged F150. Should easily make 500 rwhp without anything but a tune.
I say you should just stick with the V8 if you're into modding it that heavily anyway. You can throw a new bottom end in if you blow it up, why stick with the V6 if you don't like it ?
