    Ok weird situation. My Tundra passed 109k miles a few weeks ago and I'm nearing 110k miles. I haven't done anything special, no new parts or upgrades. Just had the oil changed and tires balanced/rotated about a month or so ago.

    But I've felt a noticeable increase in drivetrain performance with the truck. Increased low end and high end torque. Any thoughts? I'm definitely not complaining, I think its great but just curious why the old bird is now a spring chicken.

    I thought about that and it kind of lines up with the recent hot weather that just rolled in but this didn't happen last year when it was hot.

    And normally its the colder weather (colder in TX = 60 degrees F or below) that has an effect on the performance in my experience.

    Yours may be, but is the mechanic's all accounted for? If it's not, let me know what the hell he's taking. I'd like a shot at whatever he's got! :spy:

    Yeah that's going to be an awkward conversation. :gossip:

    And I don't think that's sanctioned by man-code.

    No, you may be right on that. I don't think Sean Connery, Burt Reynolds, or Bruce Willis would approve. Clint Eastwood would just shoot me and/or run me over with his Gran Torino.
    Good call.

    Tires rotated and balanced would help if they were off. Driving straight and balanced may give you the thought of performance improvement.

    Don't think it's that, still going to fuel up at the usual watering holes.

    No, went to a reputable shop down the street.

    Yeah, I noticed the shake is gone at higher speeds but doesn't explain the low end torque. I feel like a jerk cuz I'll tap on the pedal and my truck heaves ahead of the other cars when the light turns green.

    I've been getting the regular octane. Summer blend might have something to do with it, but again, this didn't happen last summer.

    Ok, this is the only scenario that explains everything. A brief hole in the ozone layer allowed trace amounts of radiation through that then bounced off our dining room window towards the driveway and zapped the antenna which then transmitted straight to the ECM, causing the Tundra to become self aware and tune itself for optimum performance. Now I just need to make sure it doesn't turn on me.

    On a serious note, it may be a combination of the above mentioned items. I remember now I also had the rear diff fluid changed out, maybe some deposits worked themselves out of the gears or something. I also did a SeaFoam treatment at about the same time, maybe a delayed reaction to that.

    A lot times it's your shoes. Trucks preform a lot better when you're in flip flops. It's science.

    Strange new symptom I just noticed. Improved MPG, I averaged 24 mpg on the highway yesterday on my way home, very strange because I've never been able to average over 20.5 mpg previously. Anyway, that kind of points to maybe a cylinder issue that may have cleared up.

    Second image just shows how hot it was yesterday.

    I'm firmly convinced that as we get older our perception of speed changes. This is evidenced by all the codgers around here going 50 on the freeway. Maybe yours just kicked in all at once?

    Update: Has returned back to normal. Getting 16-18 mpg on the freeway with cruise control. I used my scanner and no codes, I even checked each cylinder with no misfire counts. Might be a fuel injector, fuel filter or fuel pump issue.

    My usual sea foam routine.

    1/3 bottle in the vacuum hose, let it sit for 10 min
    1/3 bottle in the gas tank
    1/3 bottle in the oil (only for about 1,000 miles)
