What if we told you that the 6.0-liter LS-based V8 has been finding its way between the fenders of your favorite GM truck for almost 18 years now? And while it has seen many design improvements over the years, the original blue print is old enough to head off to college any day now. But it’s for good reason, they make great power, they’re dependable, and most importantly their adaptable.

However, in the realm of aftermarket parts, the 6.0-liter mill is often forgotten or lost in the mix. But we’ve got good news for you, DiabloSport hasn’t forgotten about the dependable bullet and has just announced that they will be offering both the inTune i2 and Trinity tuners in options that are compatible with the 6.0-liter engine.

Not only did DiabloSport not forget about the 6.0-liter guys, they are pulling out the heavy guns. The i2 and Trinity allow you to run up to four separate tunes at the touch of a button. The first tune is a modified stock tune, which allows you to adjust custom parameters without a change in horsepower level—great if you want to add wheels and tires, but what if you want more power?

That’s where you step up to the upper echelon tunes. The first is even a “MPG Booster” which adds 30 horsepower and 25 lb-ft of torque all while offering you more miles between the pumps. Next is the “87 Octane Performance Tune” which will add 30 horsepower and 40 lb-ft of torque to the equation—nothing to sneeze at, that’s for sure.

The top of the tune heap is DiabloSport’s “Performance 91+ Octane” tune which offers a remarkable 40 horsepower and 45 lb-ft of torque gain over your stock setup. Pretty astonishing considering back in the day those kinds of gains required a cam swap. But what if that still is enough for your insatiable lust for power? DiabloSport offers a tune for trucks that are equipped with FlexFuel that will gain you 50 horsepower and 50 lb-ft of torque while running on E85.

You heard that right 50 horsepower! Making this easily one of the best bang-for-the-buck mods you could ever perform on your truck. Although, DiabloSport can’t be held accountable for the additional fuel costs you’ll incur from dropping your foot to the floor repeatedly. And the best news? They are on sale now through the end of the year. Now you have no excuse to add 50 horsepower to your truck.
