I only wish I was getting close to that mileage. I just got 11.8 mpg on my last tank....maybe a tune would yield better mpg?

[bogeypro]

which tuner did you put on to raise MPH to 16.5? I am at around 15.5, but I have to drive like paw-paw to get it.

A good custom dyno/road tune using a wideband O2 sensor and hp tuners will yield far better results than any programmer you can buy or any mailorder tune you get (unless you go to the dyno after you get the mailorder tune, send the results to the tuner and have them edit the tune , then repeat a couple times to get it right for your truck). This route will end up costing a lot more as you have to go to the dyno to get the hard data for your truck after the tuner makes changes - if you don't, you are just letting the tuner guess on values to change, and by doing this they have to be very conservative as they don't want to be blowing up anyone's motor. A good dyno tune will run anywhere from $250 to $500 depending on the shop and the number of mods to your truck.

 

I have my tune optimized exactly for my truck, with the mods I have, and for 93 octane gas. So I can run more timing than stock in all conditions, which helps for a large part of the part throttle cruising mpg gain.

I assume you mean mpg, not mph. Hp tuners, way better than any handheld. Don't get me wrong though, if I drive the truck hard, I will be in the high 15's for the tank. Stop and go, and reving above 2000rpms or so just kills gas mileage on the truck.

So for anyone who has not yet had a chance to run against a Ford 6.2 Raptor here are the details. My friend just recently purchased a 2012 Raptor and after he ran a tank of gas through it, it was time to run the 6.2 NHT against the Raptor 6.2 Now I do have a K&N intake and a Magnaflow muffler; however, we all know the gains are minimal and more for the beefy sound. The Raptor was completely stock and a capable driver at the wheel. There was also a Mustang GT that joined the fun, mods unknown, year what looked to be 2010+. So, all three raced from stop light to stop light at three different lights, all with the same outcome. All three cars roasted tires at the start and there was no question my 6.2 NHT got them both all three times. I was in automatic, not the manual shift mode with the traction control off, same with the Raptor. All three races I got the Raptor and GT by a full truck length. The Raptor and GT were side by side. I shot out from a dig with the 3:73 gears and didn’t look back. It was a fun experience because the Raptor was the only truck I have yet to run against. The only truck to pulled on me so far have been a dodge SRT 10 (Obviously haha) and a really quick Lighting that had bells and whistles. I have a feeling after a BB tune the lighting will be closer; however, the SRT 10 is a BAD TRUCK. Just thought I would share will you guys. Later.

My mods in my sig will EAT srt-10's and I have 3:42's and 20's!

[SLT for me]

Still breaking in my '12 Sierra ec NHT so I haven't given it all yet, but does the traction control on/off make any difference in acceleration? Obviously tire spin will slow you down but does the traction control limit the power?

[gonzoid]

dozens of kill storys yet still no video,someday someone is bound to be armed with a smart phone and not affraid to use it.

Defiantly not afraid to use my smart phone, but didn't have a person riding shotgun to record for me. Something tells me racing from stop light to stop light while using an iPhone is probably not the best idea.

? Not an expert by any means but I prefer it off.

Your stock 5300lb 403hp truck beat a 3500lb 315hp car? WoW, good kill that car should run about .7 seconds quicker than your truck in a 1/4 mile.

Yeah I am no expert or experienced racer by any means so must have been the driver. I still will take anyway hahaha

Found this on you tube a 6.2 vs ecoboost

 

 

 

 

the eco boost didnt build boost at launch,had he it would have been a little tougher

[EX-F150 owner]

I don't think so lol the 6.2l was pulling ahead the whole time. No way the eco has any kind of a chance

[David_L6]

Finally got it today! Nothing fancy but it will serve my purposes. Not many options other than the Max Trailering Pack.
