First-Ever Tuned C7 Corvette ZR1 Makes Impressive Power Gains

By -

HP Tuners and Race Proven Motorsports have cracked the C7 Corvette ZR1 ECU, and the results are seriously impressive.

For some folks, a stock C7 Corvette ZR1 is more than enough. And that’s fair, given the car’s already high output of 755 hp and 715 lb-ft of torque. But for the rest of us, even those kind of numbers aren’t enough. Combine that with our morbid curiosity of what this mighty Corvette’s powerplant is truly capable of, and you’ve got a dangerous combination. One that’s also led RaceProvenMotorsports to crack the car’s ECU and give the Corvette a proper dyno tune.

RPM claims to be the first in the world to do this deed, and we have no proof to refute that claim. But we are guessing that not a lot of C7 Corvette ZR1 owners are out there seeking more power just yet. Regardless, as you might imagine, playing around with timing and other variables on the stock LT5 produces some very impressive results. Even if this car isn’t 100% stock, as it’s already fitted with headers and a GM Performance intake.

The car baselines at 662 hp and 669 lb-ft of torque. Which is right around what we’ve seen from other stock cars. But after tweaking a few variables, those numbers jump considerably. When it’s all said and done, RPM is able to extract an additional 87 hp and 95 lb-ft. The end result? An impressive 749 hp and 764 lb-ft at the wheels.

But as is often the case, that won’t be the end for this particular Corvette. The crew is planning to install a Cobb blower, for starters. Then they’re going to add meth injection and a new cam to push those numbers even higher. So if you’re a numbers junkie like we are, you’ll definitely want to stay tuned for all of that.
