Big power gains with emissions intact is what Calibrated Power is all about. For over 10 Years Calibrated Power has focused their research and development on aftermarket tuning that retains factory emissions equipment. The Black Box Tuning by Calibrated Power is a complete tuning package including ECM and TCM tuning. This device gets rid of the factory dead pedal, gives you more usable power, and dramatically improves your overall driving experience. Unlike pressure boxes and pedal signal interceptors, this custom tuning recalibrates your entire engine operation to run more efficiently and produce more power.

The Black Box On-The-Fly Tuning features 5 ECM tunes that are optimized for specific driving situations.

SPORT TUNE: This tune will net you peak horsepower and torque with 120+ rear wheel horsepower and 216+ ft-lbs of torque allowing your truck to reach 595HP and 1266 ft-lbs of torque. The Sport tune gives your Powerstroke the fastest possible acceleration, firm shifting, no dead pedal, and the biggest adrenaline rush Calibrated power can give you!.

STREET TUNE: This tune will net you 100 additional horsepower and 180 ft-lbs of torque all while eliminating the dead pedal feeling. This tune gives you the most power and torque you can add while maintaining OEM levels of reliability with fast acceleration. The Street Tune is a perfect mix of fun and drive-ability with a smooth power curve that retains the factory turbo-braking feature.

LIGHT TOW TUNE: This tune is the perfect balance of daily driving and towing with an additional 60 rear wheel horsepower and 108 ft-lbs of torque. The Light Tow Tune has a very smooth power curve that is still fun to drive. Designed to tow less than 8,000 lbs. the Light Tow Tune features a customer "Smart EGT Control" that will automatically manage your EGTs for safety. The air fuel ratio limits built into the calibration limit soot production all while giving you enough power to shift up and throttle back. The revised pedal sensitivity gives you low speed trailer maneuvering and the ability to back up your tailer without lurching.

HEAVY TOW TUNE: This tune is perfect tune for that extra heavy load you need to move. With an additional 40 rear wheel horsepower and 72 ft-lbs of torque, this tune is optimized for towing 8,000 lbs up to your trucks GVW. With the same revised pedal sensitivity and EGT control as the Light Tow Tune, this tune will get your heavy trailer moving more quickly and allow you to lug in the gear you want while towing. The factory turbo brake is also retained and will function as normal.

OPTIMIZED STOCK: This tune is the perfect tune for when your buddy drives your truck. An additional 20 rear wheel horsepower and 36 ft-lbs of torque, this tune is only slightly modified from stock.

TRANSMISSION TUNING INCLUDED: The ECM Tuning provides smooth shifting and superior drive-ability that makes your truck feel more powerful and is the best tool to ensure your engine is operating within its preferred rev range. Quicker shifting means less time between gears and more time putting the power to the ground. This tune prevents short-shifting in performance applications and improves clutch holding capacity with increased line pressure that keeps your truck in its power band when lugging up a grade. The torque converter lockup strategy helps you put power to the ground when you need it the most. If you have larger tires (35"+) or any modification that impacts operating RPMs, transmission tuning is especially important.

Way too small with very little stretch.
I ordered a size 4X to make sure they were loose enough. The ones I received are like a size 8 very small.

If you haven't switched to boxer briefs, you're missing out :)

I figured I ought to provide a review, something I'm not prone to doing even though I often/always bank my purchases on item reviews, since I just bought me a second set of these underwear because they're just that good! I bought my 1st set of these 2 months ago because I was on the hunt for some new comfortable underwear and omfort was my main criteria. Wasn't aware that I was dealing with some health issues that was causing a fair bit of internal inflammation, just knew that I had had enough of basically everything I had at the time because they were old, ratty looking and even my all-time favorites had begun feeling too... something... not exactly too tight, yet they just weren't very comfortable anymore either and I didn't need that kind of extra stress in my life. But. I'm a barely-makin-it domestic violence survivor. Sure, I'm super proud to have gotten as far as I have in this world (considering that post-separation psychological terrorism and torture continue to thus day, 5 years after I broke free) but, by rights and family-rearing, I should be living in a whole different world right now... which is my way of saying that money is extra, EXTRA tight in my house...and yet, I still have "caviar tastes", ifykwim. Lol. And, frankly, neither I nor anyone else should have to scrimp on comfortable, classy-feeling, fashionable clothing no matter how small our clothing budget may be. I was spurred to check out boxer briefs for women after reading about a few different women's favorite brands in the comments on soneones IG post (that must have been in regards to underwear, but heck if I can remember the details). So, off I went to scout around on Amazon to see what this "boxer briefs" business was about... desperately hoping that the term was not just a rebranding of those "hipsters" things. I am 46yo, 5'10" (potentially closer to 5'11"... not something I care enough about to know for certain, lol) and, clothing size-wise, my whole adult life I have consistently been a 16-18/18-20, top to bottom, with a shape that seems some what apple-ish at the moment but has, in general, always been more hourglass than apple. Also it seems as if I might have rather freakishly high hips, lol... not really, but for reference, when it comes to pants or jeans what generally passes as "tall", usually a 33"-34" inseem, fit like ankle or cigar length pants on me. But evidently I don't just have long legs, no, this momma's body seems to also have one heck of a long, tall pelvis which I did finally measure to figure out for sure but, prior to that, I could tell based on the way that low cut underwear like bikini & hipsters, and any form of low rise pants, barely make it north of my low lying c-section scar location which, for those who can't relate, is basically at the top of my hooha or just at the point where my belly and my hooha meet. And because that point on my body is not even remotely close to my "hip" area such items basically fall right off my body unless they're super stretchy and I deliberately hike them up to my hip area which I put up with in my 20s and 30s, for the sake of fashion I suppose, but which was and is quite ungodly uncomfortable, and... basically... I am so over with "uncomfortable" anything (men included, lol.) In both cases I bought size 11, though, if I'm being honest, I am certain that a 10 would have fit well, too. And who knows, a 10 might have been just as comfortable or even more comfortable than the 11... but, I didn't take bother taking the chance to find out when I ordered my second set because the first set (size 11) made me so unbelievably happy that they literally changed my views about underwear for life. This whole "pants come off after work" thing or the memes about people working from home (due to covid restrictions) and not wearing pants never jived with me prior to having these boxer briefs, but now... omg... these things are super inexpensive and somehow still suit my somewhat "caviar taste" perfectly (have a good handfeel and are just so unbelievably super comfortable), PLUS... they're opaque and they basically fit (and look) like I'm wearing a loungy pair of bike shorts, so... yeah, I've spent some time over the last 2 months actually chillin in my house in my freaking underwear!!!! Life. Changing. :D
