I don't know how you can drive @50mph and not get run over even on 4 lane roads, just pulled my 5th from Regina this past summer and 110kph was about as slow as i could go with out getting run over, so much for that, I have tuned lots of gas engine's in the last 50 yrs and one thing you got was extra power but milage did very little change and those engine's were done by a good engine builder in Selah Washington that are famous for the circle track racing crowd. Just my thoughts but I only pull with an ole 5.9 400hp Cummins that is chipped.


98 Mountain Aire 34' 210 Cummins Puller and 2001 dodge dully with all the toy's, 400 + hp pullin a 2001 32.5' Okanogan 5th wheel, new to us after 5 yrs with the 28' Travel Aire. Lots of fun.

I don't even get honked at.

The thread is about saving fuel. Apparently that just doesn't happen with "tunes".

What does the chip cost? How much fuel $$ is burned in a year?

Hi,

With fuel prices going through the roof, is it time to "chip" the V-10 engine with the idea of saving fuel? RV is from 2004 so a four speed.

I do drive 49 mph (78 kph) and do get 8 to 10 MPG doing so.

I can not afford a replacement engine, so I do not wish to take any risks.


Today, here in California (Los Angeles area), I just bought Chevron (Pearson Fuels) E85 for $3.85 a gallon. (over 100 octane fuel) Regular 87 octane fuel was $5.50 at the same station. Do the math. See what works best for you. I've used up to a 30%/70% mix of E85/87 octane in my 1999 Class A F53 V10 with no drivability issues. There is a slight hit in the fuel mileage, but hey, . . . at 7 to 9 mpg already, that's not what's bunching my undies.

Chip tuning for economy/power (while meeting emission standards), . . . . please, . . . tell me when to stop laughing. IMO, these "chip tuning experts" will never beat the Ford factory engineers with repeating reliable verifiable data. It's all marketing and advertising XXXXX.

Driving 49mph on the highway might be more ridiculous than thinking a tuner will save you more money in fuel than you spend on it…

The chip and tuner folks will promise you more power, better shifting patterns and improved mileage...[emoticon]

The only one that is likely to be true is a slightly different {not necessarily better} shift pattern. The energy in a gallon of any fuel is finite. You might maybe get a little more power and you might maybe get slightly better mileage but no way you will get both.

Keep up on the routine maintenance, when you want/need more power put your foot into and drive it as the engineers intended and if you want better mileage slow down, run the proper psi and unload any unnecessary gear.

Greater efficiency is at your fingertips when you simply engage the Tow Haul mode. The weight of any E-450 is sufficient to justify the use of TH even if you are not towing... you are hauling 14,500#. Now put the money you just saved into a fund for any unforeseen repairs that may be coming down the road.

As always... Opinions and YMMV.

Excellent information and advice!

As usual the people that have never used a tuner know more than the people that have used it and can tell you the real before and after differences.

On the other hand the folks that plop down serious bucks for a chip or tuner think the chip tuner folks know more about their vehicle than the manufacturer... Just sayin.

Even I can tell from driving my Excursion and now my MH that they don’t have the customers best interest at hand. They make a one size fits all tune, they go into everything from pickups, box trucks, dump trucks and bread trucks as well as delivery trucks. They are all loaded to different weights. Mostly empty. Where a MH is built and is mostly loaded all the time. So the performance in an empty box truck is far different than that of a loaded MH.

Or maybe they have used a tuner and are sharing the results.
