MPG with MPT

[BangBang]

My driving does not change with or without the tune. I have gone back and forth and tracked each closely. I definitely burn more fuel with the tune than without. Regardless what are you saying needs to be recalibrated?

In your first post you did ask if you are getting on it too much.
How's the mpg difference in your driving style between Sport and Regular modes?

I never drive in sport enough to track it. Mostly stop and go traffic with the exception of a quarter mile stretch of on ramp in each direction to and from work.

I just can’t inagine I am the only one seeing a drop in mpg with a tune compared to stock.

I didn't see any drop when adding MPT.

Then I guess it is me not adjusting my foot for the increased throttle response.

Ahaaaa! My bad! I forgot about the throttle ramp up with the MPT basic tune. I have a linear throttle response, so yes if you don’t go easy on the throttle at tip-in you will likely waste a whole lot of fuel for that fake power feel. In this case you will need to go especially easy on the throttle off idle.

So with the linear response the harder you press the more power you get? Is it possible to have linear in normal and ramped up in sport?

Yes.
I'm pretty sure mine is set up that way. I only run it in Sport when racing, usually at WOT, so... You can email MPT and ask for a new tune version with liner throttle and you should be good!

I generally run mine in “Normal” mode the vast majority of the time. Before the MPT PRX93 was installed (first 5,000 miles) the dash read 17.2 mpg, currently I’m at 15.4 mpg.

The biggest thing that I noticed with the tune is that the truck stays in the power band more, rather than shifting up to 10 as quickly as possible. It seems like I need to be above 48 mph before it shifts into 10 with the tune in normal mode, stock was around 39 mph if I recall.

Yes, I am accelerating more with the tune, but I believe this is also contributing to the lower MPG than initial per computer (FYI, my over-all MPG shows at 16.1 in the trip, the 15.4 avg is the instant read-out which has never been reset).

Those are good numbers.

It’s mostly all 45 & 55 mph roads where I live - very little stop and go traffic.
