Wait4me gas mileage tune

jaslo · October 1, 2006

I have this tune on my 2001 chevy silverado, I put the stock intake back on, cleaned the MAF sensor and I am still getting about the same gas mileage if not worse than with the K&N on there. I am wondering for those that do have this tune, what kind of gas mileage are you getting and what mods do you have on your truck? I usually get around 18 mpg

On the Highway I am getting about 18 now, which was down from when Mine was fully stock.

Now if I reset the computer while I am driving on the highway, I can get it to read about 20+ mpg, over a distance. This is at constant HWY Speeds without getting up to them, as I am already up to speed and going when I reset the computer.

I am getting better now around town though, I am up closer to 16 mpg. This is in a 2003 Suburban 4x4 LT with all the options and the 5.3 engine.

I also run Denso Iridium plugs in it. I had put the K+N FIPK on it, but that killed my Gas, it took me down to like 11 or less. I removed it and put the stock replacement K+N back in, then sent the FIPK back to Summit Racing, and they refunded me on it. I then took that money and bought the tune, and I love the tune. I have so much more power off the start and while passing. The car will now snap your kneck when you floor it from about 20-30 mph pretty hard. I love the new found power it has. The engine just sounds alot stronger with the tune.

I also notice that I hit the gas pedal a lot more since the tune, so this may be why I am not seeing that much of a difference in the gas.

I get 20.2 average on my trip to work 145 mi takes 2 hours 5 minutes and i get better when towing 16-17 mpg and in the city 18.9 mpg have the economy tune and nothing else. Lots of passing power.

Wait 4 me tune is a good tune with a stock vehicle.

Sounds like 18 mpg is the average here. I am planning on putting in 89 or 91 octane, reset the computer and see if that makes a big difference or not.

I hit 22 mpg with a stock tune on my '02 Z71. AC on, keeping the cruise set at 65 and under. This is highway. In town, I could never control my foot long enough to get an accurate reading on how well I could do, and I averaged just under 14mpg on any given tank.

On this truck, those are dream numbers

Before my tune...I had about 16.5 in the urban driving, 14 at the absolute worse (hotrodding it everywhere), and close to 21 on the highway. of course I have the 4.3L. Dont know about the tune because I have not got the relearn done yet.
