Good experience with diablew intune on a 2014 Silverado. Both engine and shift points. Canned tunein the intune was fair but custom by diablew was much better.

I did a muffler/flapper delete on my truck. The sound is much better than stock and lost 22 lbs of muffler flapper. The sound in v8 mode is pretty good definitely not to loud. In v4 mode it makes a weird flutter sound not unacceptable but not great either. If a guy were going to tune the v4 out the v8 sound would be a good inexpensive option. A good friend with a 2014 5.3 installed a cat back corsa sport. He feels like it is a little to loud on cold start and acceleration The sport corsa is just a little sharp/loud for his liking .I am sure others would like it even louder just depends on what you are looking for.. He liked my delete better than his system. He hopes the muffler shop will let him swap out the sport muffler for a touring muffler. Hope this helps.

A good friend had a diablew tune done and the low end throttle response and shifting points feel so much better. It doesn't even feel like the same truck. Going from the diablo canned tune 87 octane to the custom 87 octane was night and day difference.
