Tuner recommendation

Installed K&N CAI and Corsa S catback on 2020 Suburban RST 6.2L, now want to program via tuner. What best and easiest tuner that’s plug and play? Thanks! 

I did search forums with no luck. 

And do I need a tuner with these mods?

No, you don't need to tune anything for those mods.


HP Tuners is available for the 2020 model year Suburban but that is a do it yourself tuner that you must learn how to use.


You would have to see if people like Diablo or HyperTech make a tuner for that truck. Just know that anything you do like that will void your warranty. They can see anything you do if it went into the dealership for warranty work.

Tuned my 18 5.3 with Diablo sport and had a custom Diablew tune done about 10k miles ago. Couldn’t be happier. Yes I believe you do take a chance of them voiding your warranty but it also depends on what needs repair also. IMO it’s worth the risk. You have to see what works for you.
