    • Good for 8.1 with 4L80E in 03 2500 Yukon
Very easy to use. Flashed my 8.1 Vortec in my 03 2500 Yukon. I always run premium because I mostly tow with it so I put the 91 Octane Performance Tune on it right out of the box and I noticed a little quicker sweep through first and second and noticably crisper shifts. There's still adjustability left to further firm the shifts, which I'll play with till I like it. I haven't tried the towing tune yet to comment on that. Very cleanly executed, easy to use and effective product. I'd pay full price for it again for a different platform if I ever change trucks. 10/27/21 update Ive been using this a lot longer now and am even happier. Ive found the shift pressures that Im happy with and I have the ability to reenable the Upshift Torque Management setting when I flash to tow mode. Ive used all the modes and while I didnt notice a significant difference in the fuel milage setting, I do notice performance mode and towing mode. I dont expect fuel milage improvements owning an 8.1. I would like the option of being able to used dial in up to +4 or +5 degrees of timing to fine tune performance mode: but Im pleased with this as a its a daily driver and a tow vehicle. I'd still buy one again. ... show more

    • Seriously woke up my LLY
I bought this to help with fuel economy during the $7/gal diesel fiasco.. I went from 14 mpg to 19 mpg immediately. It basically paid for itself within the first 8 weeks of owning, I burn a ton of diesel. My truck gained big power although, I don't beat on my truck. Towing 10k lbs daily, like it's nothing. I put it in the performance tune for non towing days and I've seen 21 mpg after 6 hours of highway driving. Absolutely zero issues so far, 2 years running. Great investment!! I will say that if your trans has a ton of miles on it, DO NOT floor it on the highway. You will limp the trans in 5th. If that happens, clear the code to reset the system. Then just don't floor it on the highway. Or, smarter option, tune it down a level if you can't manage the urge to floor it lol ... show more

    • Wake your truck up!
My 2016 gmc 2500 hd Duramax loves this programmer! I put it in the performance tow mode and it absolutely woke the truck up! Plus my fuel mileage on the freeway it’s unbelievably better.

    • Probably the worst tuner to date.
Review Image by kurtis h.
Does not work. Will not allow me to tune. I have the Correct truck it has in listing. I updated it and tried everything. Not worth $400+ for a DOA unit.

    • Superchips Flashpaq F5
This F5 tuner works great on my 2011 Silverado 5.3ltr. I'm not looking for performance as much as AFM/DOD Delete, and shift points, as well as RPM idle adjustment and speed limiter. Fine product, so far. Just had a week.

    • Great
Installed on my 2016 Chevy Duramax and it made this thing come alive! I installed the Performance tune and it really made the throttle response quick and shifting through the gears faster as I hammered down on the throttle. I've always used the Banks on my previous diesels but am blown away by the Superchips tuner. Be aware that removing the speed limiter also disables your engine brake and cruise control so I left mine enabled. I really only wanted the extra power for accelerating onto the interstate and overtaking slower vehicles which is where the Duramax really lacks because of the slow throttle response. ... show more

    • Great product
Had a tune file stuck in my truck 2005 duramax and it wouldn't let me use the programer. Called the tech line told them what was going on and that I was told to take it to a dealership to get the ecm flashed and they said they would write me a tune to over ride the issues. I will be using them again since they was upfront and honest about things and it saved me money as well. ... show more
