Superchips, Bullydog GT, or Diablosport Intune I2 for 2015 Tahoe?

Which would be the best canned tuner for a 2015 Tahoe? Looking to wake engine up and hopefully keep fuel mileage. Looking for some pep and improved drivability. Thanks!

Diablo seems to be the front runner with the best combination of price, customization and flexibility. For around $400~$450 you get the In Tune I2 and can use the "Canned" tune or modify the available parameters to suit your needs. If you need to take it in to the dealer you can return to the stock tune in 5~10 minutes.

I purchased mine and installed it at 1000 miles about 10 weeks ago. I am very pleased with the results.

Would the dealer be able to tell that this was done?

Not if you take it back to the stock tune before taking it to the dealer. I've taken mine back twice without issue. Each time I restored the stock tune and re installed my custom tune after picking it up.

FYI dealers can't deny warranty work for you modifying your vehicle, so it shouldn't matter if they can tell it's been tuned or not.

It's on the dealer to PROVE the modification caused the warranted part to fail per the Magnuson Moss Act.

Most handhelds can only tune the ECM for the newer vehicles (and tables are limited). You are missing out on half of the tune with not getting the transmission done.

I've been very happy with the Superchips Flashpaq. It's a bit cheaper than some of the others and it does quite a bit. It also does the transmission with the canned tunes. Updates are always free and tech support is awesome.

The Superchips will not work on the 8spd, and not all the 6spds.

Good to know! Thanks.

Any input on the Bullydog GT Platinum?
