I don't know about this particular performance chip, but the 5 STAR TUNE was definitely NOT
a waste of money!
AT $500 5 Star was worth very penny. Our 2015 V-10/5 speed on the F-53 chassis had an awful shift pattern with the RPMs roaring to near 4000 just to go over an overpass. After loading the 5 Star Tune there was a small increase in RPM that was hardly noticeable. We always towed a Jeep Unlimited & the performance was great.
Also, 5 Star will customize the chip if you want it adjusted, great customer service.
Go on line & read the reviews from 5 Star Tune owners, it's top notch! If the SCT Tuner does as good you'll save some money, but I'd highly recommend a performance chip.
