No I haven’t had one done yet however there used to be a speed shop on Ashley Phosphate behind the new Mr. Corvette. I have a tune prior on a Silverado I sedto run around playing with and got referee to a guy by the name of JP from the guys out of that shop. Any I did get with JP and what he offered back when I had this done was he would connect his laptop and software up in the vehicle and ride with you for a couple hours getting your driving style, recording real street pulls, I even went and changed fuels while on his watch and he adjusted for that as well, the only downfall about that deal was he just had to set it up for an average conditions and driving styles because I didn’t have any devices to switch tunes for the different applications I may find myself driving under. That’s was the big motivating factor with going with DiabloSport this time because it came with 5 different tunes to set the truck under labeled or categorized by fuel octane like 87, 91, 93, 100, and one labeled Cold Air Intake or something like that falls near the bottom or less mild spectrum of the tunes, and then I could adjust a few details just a couple points in either direction from the base start program. Again all explained to me to be generally safe I mean obviously it wouldn’t have been recommended nor “Safe” to run a 100 octane tune with 87-89 octane but certainly could drop 5-8 gallons of 110 and set the tune to the 100 program and notice significant improvements. Again under the pretense that doing just these things would still keep the engine within is safe operating parameters and with all the critical safety parameters activated and in place to prevent catastrophic damage/ failures, that was the pitch I was informed when I was considering another performance tune experience. And I like to think that most of the time they get it right , because they are in business of tuning street cars with this package they seem to be successful at and knowledgeable about. Maybe I just received the one in a million that wasn’t programmed properly or maybe mislabeled idk that’s the reasoning behind me asking them to look through the files and verify it is indeed safe before I used it again on the second engine. They convinced me that my first engine failure was simply coincidence or it was just its time to go. Keep in mind also I didn’t tear down and investigate the first engine damage when I swapped it out i just built a roll around cart to support it off the floor and rolled it up against the wall in my shop and covered it to be rebuilt at a later date for a later project. I only pulled the heads off and started investigating after the second engine to discover they both experienced the same abuse.
