I ran the 87 Performance out of the box. I didn't experience or feel a big difference, but I could tell there was more to be had on the 93. That day, I drove the remaining 100 miles out of the tank. Filled up with 93 and loaded the 5 Star 93 Performance tune.
There was a noticeable improvement of the "driveability" on the 93 tune over the 87 tune, which made me very satisfied...for what the truck is capable of. Even if the 0-60 wasn't improved on 93 (although it was slightly), the 93 tune was worth it to me. The shifts are firmer, better mpg, and throttle response is a huge improvement.
Keep in mind, that I've owned several supercharged Cobras, ACR Vipers, and 9 second quarter mile motorcycles. Therefore, my "performance" expectations of any truck would be laughable...afterall, many stock sports cars and motorcycles would still be faster on the street than a 1000 HP Raptor. Don't get me wrong, the Raptor is one badass vehicle and one of the...no, make that...THE best, overall driving vehicle that I've ever had. But, it is a heavy truck, not purpose built for on road...and any high expectations on the street, they're going to be in for many light-to-light disappointments no matter how much power they have.
So just let the guy in the vette pull up beside you at the light, give YOU a thumbs up...and then let him roll on. With or without a tune...you already proved what you needed to, before the light even turned green.
