Im going to get the Flashpaq, dont need the fancy one.

Both can be used on future GM vehicles.

The Flashpaq seems great, please let me know what you think of it.

I just used a Diablo Sport tuner on my 16 GMC with the 5.3L. The tuner itself was pretty easy to use and has a lot of great options. I used to to increase the performance of the truck, make the shifting more firm and removed the displacement on demand. The tuner gives you countless options to adjust your trucks programming to your liking. Also, as your build progresses, you could contact Diablew and have him do a custom tune to really make a difference with your truck. The people on here seem to really like his work and a friend of mine had his Camaro tuned by Lew and it made a big difference.

SCT X4 is best optimized for the GM line. RDP Store has years of experience with tuning high horsepower and daily driver cars and trucks. The SCT X4 is our go to handheld programmer for the GM line of cars and trucks. Hope this helps. WE will even be able to do a remote custom tune for your truck as well. The custom tune is free with purchase of the SCT X4 from RDP Store.

SCT X4 may be the best, but you might have the worst web site. Unable to access it, get a huge stupid message to hit refresh, which I did, but keeps coming back up, like a dog chasing its tail. Never saw or heard of this refresh required every time visiting a site before.

The reason for a refresh is to clear all cokkies that people may have from being on the site before as we add around 100 new lines every day

You don't seem to understand, even after refreshing, can't access the site.

RDP might have a good price on the SCT X4, but the tune I got for my 2015 5.3 Silverado isn't very good. Get a error message popping up all the time. They basically said I was complaining too much, and left me hanging!!

There tune Sucks!!!!

Most handheld tuners will not tune for the 6spds, the only software suites that currently tune for the 8spd are EFILive and HPTuners. If you don't tune for the TCM, you are missing out on half the tune.
