I'm a daily-driver wanting to get optimal performance on commuting and towing. With 6+hrs invested in research, I decided to give those guys a call. Within 15mins I purchased a SCTX4 for my 07 XLT screw.

 

I just got my tunes with MPT. Granted I have less than 30 miles under it. (stupid weather) Emails, shipping, and tunes came quickly. Have fun!

 

MPT are great folks.. I have close to 20k miles with their tunes.. Also have about 20k miles with 5 star tunes.. Both are top notch companies

 

Thanks, I received a product shipped notification this morning, looking very promising.

On your tune's, did either of you notice an increase in MPG when driving conservatively? I traded-in my Explorer which was meticulously maintained when driven easy I got 20mpg, I hope to get close to that with this F150. Grant it there's many other variables in affect to achieving that. I'm an old 70's prodigy when steel oilburning 4-bbl squirting atmosphere polluting devil's were abundant. Back then and up to now I found 32psi cold gave me the best ride at a competitive MPG both in my cars and SUV's. The F150 on Michelin's feels good at 35psi cold, I plan to drop it a few pounds to see if it's good there too and how it affects the mileage.

 

Its hard to get good mileage with the MPT Ecoboost custom tunes, because you want to put your foot in the floor all the time, I didnt have that problem when i was running the stock tune ..

When i had the OEM Michelin tires with the MPT tunes and cruising down the road at 70mph it would always pop off 20 to 22mpg. In town around 18 to 19mpg. I went with 275/65/18 Coopers when the 265/60/18 Michelin's wore out and it dropped my fuel mileage around 2mpg. I can still get 20mpg pretty easily when driving good

With your 07 i wouldnt count on the 20mpg mark but it shouldnt be to far off.. Maybe 18-19 mpg

 

To be honest, I am not really concerned with mileage as I am performance. My daily commute (5-8 non highway miles) and remote starter kills the mileage away. Plus the rim and tire combo I run isn't very gas friendly. As for tire pressure, I keep mine around 40 psi.

 

For best mileage, wear, and safety, run stock type tires at the recommended pressure on the door jamb. You may find that it's higher than 35.

 

KRC, I completely understand. The sticker said 18 hwy mpg so that's the number I'll shoot for. I'll give it the ole'maintenance ritual, if it best those numbers great, if not, great.

I'll keep an eye-out for a take-off set of newer model aluminum wheels. That and a different muffler maybe the only mod's this truck get's.

glc, 35lbs is what's on the door jam. I'll run that on my SUV's and 32 on my cars. 35 on these Michelin's are giving me a comfortable ride. I'll leave that alone but the ornery'ism will have me try 32.SMH

 

If you run them underinflated, the handling can get mushy. Today's tires are worlds different than they were in the 70's.

 

I agree, BUT 32lbs hadn't been a problem on any new tire that I've run those pressure's on yet. From the 20" low-pro tires on the Mercedes to the 17" tires on my trucks. I'll bump the rear up 4 to 6lbs when I'm hauling something in my trucks though. Gas mileage doesn't suffer either just a more comfortable ride.

 

My 08 f150 was 35 psi on 17 in steel wheels and it was a good ride. Different tires feel different of course tho. I had the stock Hankook dynapro ATs, Bridgestone dueler ATs, Yokohama Geolandar AT-Ss, and then general tire grabber HTs. Best overall was the grabbers. I hated the Geolandars. Handling was slow and mushy. Bridgestones were good all around too but not great. Grabbers weren't great either but they felt the best. My ram has the Goodyear Wrangler SR-As and they are ok(20" wheels) but the truck calls for 39 psi cold. I put them all at 41 so when it hit negative temps, they dropped to 35. Now it got warmer so 3 are at 42 and one is at 39. It's not leaking even tho it seems like it by what I put. My girlfriend has an 06 ram and had wrangler HPs for the whole time and thought they were amazing til one blew on her somewhat prematurely. She replaced them all with "wrangler adventure all terrains with kevlar" yes that's their name lol. Amazing tires. Very quiet and nice looking tread. Good grip in snow and ice. No joke it barely gets thru stuff in 2wd that her others struggled but got thru in 4wd. When my SR-As wear out, I'm getting the ones she has.
