Just installed Range device, potential issue

[scomis]

When I bought the Tahoe a couple months ago, my friend gave me new plugs for it. I put them in on Friday and WOW what a difference. Feels like a whole new rig! They are the Bosch 9602 (which I have read that people have low opinions about), but they were free and seem to be working fine. With the Range and the new plugs, it's really hard to keep my foot out of it! LOL

I've had a Range Tech for 10 years now and it has electrical issues but never a mechanical one. The rear tailgate won't open or Truck won't start which just unplug and reinstall always fixes it. The data bus gets confused at times. I unplug it every night because it can cause a small battery drain but I won't give it up because I like V8 modes rather than engine issues from lifters. Once a year I let it run in 4 cylinder mode for 2 drive cycles so it will pass emissions in my state then back to V8 mode again. Best money I've ever spent plus I run a custom exhaust which sounds terrible in 4 cylinder mode.
