    I wonder if that loss of boost is the turbo, the tune or both.

    The cost of used trucks is so high, it's almost better to lease a truck for my needs. Been thinking about 4x4 for winter and the camper in the summer. Keep my Focus for summer.

    What truck do you have? 2wd?

    I have a set of lowering shackles I bought from a member here for my 13 a couple years ago and never installed. Mines a FX4 so I’m now looking at lifting. There yours for $50+ shipping if they’ll fit your truck! 2” drop.

    Thanks, but I just finished fixing it. I removed the stock spacer between the axle and spring which lowered the back 1.25". Now I have about 1" more clearance on the back fender than the front fender so it looks level without the 'Bully Dog' look. I really wish I didn't need to modify it but I just want a normal height pickup and not one all jacked up to the sky.

    I put about 17thousand on the truck per year, overall average around 15mpg (trucks computer lies it averages missing 2 gallons which is about 1 mpg more optimistic than real calc) so the difference for me using todays prices $2.49 vs $2.93 would be about $500 per year extra. Edit, that mpg is mix driving, when on highway usually 75-80 which kills mpg and town driving lot of hills, I drive 600' vertical just on my hill least once daily, I probably average few thousand feet across day.

    While I lay in to it relatively aggressively sometimes, I rarely floor it and when I do most times is "clean it out". Basically doesn't make sense to pay for tune & tuner AND additional gas cost for 93 something rarely needed/used, other than I want it haha

    Now the 87 one takes torque 300 to 350 in the 2500-3500 rpm range and looks like about 40 horse across the rpm range, so while not peak big gains it's probably decent for regular driving conditions.

    My vehicle MPG calculator is a bit optimistic as well, around 1-1.5MPG. Highway driving at 70+ kills it, but if I stay below 70 it will get around 18 combined (hand calculated). That's after the level and wheels/tires. I'm just running P-rated 275/60/20. so they aren't terribly heavy.

    FWIW I had a 5 Star tune in my Expedition and the tow/performance tune gave me a couple more mpg. I had the economy tune and it gave me the exact same mpg. So I stayed with the performance tune. This was 87 octane by the way.

    I run same size Falken AT3W's, it really is amazing the wall feel as you pass 70. Steep downhills other vehicles are on brakes, I'm in the gas. I just can't bring myself to slow down for the mpg when I'm cutting an hour from a trip haha

    Is the Expy an ecoboost?

    Nope. It was a lowly 5.4.

    I'm running Nitto Terra Grappler G2s, love them. Honestly I'd like a bit larger tire, but the next size up are all E-rated, and a good bit heavier. It's a truck, I didn't buy it to save gas, nor do I expect "good" mileage from it. It is a tool, and I live with it as such.

    How many miles have you gotten out of these Nittos? I have them as well and have over 70k miles on them. They still aren’t into the wear indicators, but have given up a lot of grip.
    Of course I got 75k out of the stock Pirelli’s.

    Any of you had A/C problems?

    Mine is acting kind of crazy, compressor is ok, fans aren’t working. It has the dual zone with the Nav. system. I assume with the dual zone it has to have 2 separate fans or an elaborate system of doors manage the air flow. I get nothing unless the truck is moving. Then I get a little flow if I have on outside air, not on recirculate. Because of the flow when moving I believe it must be the fan(s) or the control switch or something.

    Any ideas?

    In order of most possible:
    1 - Blower motor resistor assembly (fan usually doesn't run at all)
    2 - Blend door assembly (fan runs but air isn't directed where it's needed)
    3 - Cabin air filter (fan runs and blend door directs air but filter is dirty restricting air flow)
    4 - AC/Heat control switch (nothing works at all)

    Yeah, that’s the way I think as well. The funny thing is, sometimes in the morning when it’s cool, all works perfect. Next time I shut the truck off, especially once it’s hot it will not work.
    When it works it perfect. When it don’t I have no blower working at all.

    Thank you for your input. Where can I find the blower motor resistor?
