Handheld tuner and AFM

[steve34459]

I purchased a range plugin for now. I figure the sooner I disable the AFM the better

sooner the better is correct, a 6.2L 2010 had broken/failed lifters 2x in 15 months. Too bad we werent aware of the AFM deletes.

Didn't think the 6.2L had AFM

You may be right. I'm new to all this.

Looking to disable AFM and use a tuner. I would prefer a handheld self programming module.
Have looked into the Blackbear, Diablo, Superchips and more...

Currently considering the following:

Superchips

Edge EVO

Hypertech Max Energy

Any active or past users?

I have an 09 Yukon With 191k miles daily 50+.

Can anyone vouch for either of these mentioned besides BB. I'm going to get that tuned just not right now. Anything else really noticeable or should I know about the Range unit? Any known members that used the Range for a good while now?

Got my Range plugin today. Can't wait to see if the drive is different

If you have aftermarket exhaust it should be very noticeable... When I turned AFM back on (for testing purposes due to a different issue I was having) it drove me nuts everytime it went into 4 cyl mode because it sounded like something was wrong with the truck.

I do not. All stock. I will say I like the way it drives now. I can only imagine what a good time would feel like

Sounds promising. Been trying to convince the owner of a yukon 6.2L that this is a way to go if they want to avoid a 3rd lifter/cam repair.

After reading alot about disabling AFM I have reached the conclusion that the best way is to remove the crap and delete it out of the motor. Tuning it out still has the same problem. I went to Texas Speed Performance and got a DOD Delete with cam. HP tuners will do the tuning for me. I expect to gain almost 50 rwhp and with the high milage I have I can expect another 150k on this motor as long as I don't beat it up. I have EFI Live that I use on my Duramax so I might just get another license and tune it that way....something to think about, Anyway this is my plan.
