Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

Finally got some good highway miles on the tune. Texas allows 80mph so that's what I did for 300 miles. Nothing abnormal but I got better gas mileage than I did on 19800.

 

Best MPG I’ve gotten on 2.0 final so far is 17.9. I normally get 14-16

 

That's crazy. I do 80 on my 25 mile commute two times a day and I get like 14.

 

Most of my driving is streets and I get 17.1 with that. I wish I could use the highways more.

 

Yeah, I find a lot of the MPG claims on here very hard to believe, but it is what it is.

 

My MPG seems to range between 10mpg while towing and right at or below 15mpg daily driving. 265/70/17 tires and also running OV. I must have a lead foot or something... LOL!

 

I can hit 19+ if I’m careful on my 75-80 mph 18 mile commute. That’s with 5 miles of surface street at the beginning and 1 mile at the end. Lots of overpasses. I’ve definitely hit 22 on longer 150+ mile treks at 75+ mph. That’s on Texas flats though.

 

How about this claim? I get best 14 mpg.

 

Before tune 17-18, after 18-19. However it's 95% mountain hwy. Once I pull outta driveway there no stop light or sign for at least 50mi in either direction. I am on heavy E rated. Also varies about 1mpg from summer to winter.

 

What the heck size tires do you guys have? My speed limit is 80 as well and with 32” tires (40lbs/tire) I hit 18 easily on the new 2.0. Granted I am a 91 octane, but the range of mpgs is weird...just like these trucks

 

I'm running same as you but speed is 55 so I stay around 60. My tires are 54ea.

 

MPGs depend where you live. I had a car that got 26 in Arizona and 21 in central NC. Low flat country with high quality fuel is best for MPGs.

 

Same size tires. Premium fuel for the last year or so.

 

If you can drive 60 mph you can get good mileage! I got 20.6 mpg's holding it at 60 mph under 2000 rpm's pissed off a few drivers! Once you get up over 2000rpms the mileage starts taking a hit! I am running 34's 4.88's and 2.0 premium non thx running on flat roads i can get 17 mpg's @75mph throw in any hills slopes or over passes it drops between 15 and 17.

 

I’m wondering if 91 makes that big of a difference...?

 

It depends where u live. Lots of hills where I’m at here in CA, and I average around 14-15mpg. If I’m doing just highway I can get 17mpg depending where I’m going And if I’m hypermiling like a grandpa in a Prius.

I’m on 33’s 5.29’s and about 300lbs of extra weight. 2.0f 91 tune.

 

I run 91. I think it's just vehicle dependent, which is annoying

 

With recent posts of people finding 1 or more spark plugs loose when changing them, I'm curious if this is more prevalent and possibly leading to some of the variances between vehicles.

 

How many?

our R&D Truck had 3 or 4 loose plugs. thought it was just a fluke.

 

did they know it before changing them out? warning lights? issues?
