I'm trying to decide on whether or not to add a tune to my list of things to do. I'd like to hear from anyone with experience with a tune on an 07+ Burb/XL. What kind of gains should I expect, was it worth it, etc. I understand everyone's experience may be a little different, so please chime in! I needs your input!
Any NNBS Suburban/XL owners have a tune?

I started out with the DiabloSport Predator. I primarily got it to disable DoD and do some minor tweaking. I have since upgraded to thier new product InTune. It basically does all the same stuff but much cleaner and more intuitive. It also supports TCM tuning as well so you can adjust torque management, shift points, shift firmness, etc. I'd say go with the InTune if you're going to try a hand-held tuner. Outside that... if you want a precise custom tune then I'd contact BlackBear as they seem to know their stuff and support their work.
Sorry Brian, I forgot to add that I do not know anything about engines, exhaust or computers. So...can you start over again and tell me what DoD is, and what other minor tweaks you speak of? Oh, and thanks!

Since our trucks are practically clones, I will highly recommend Black bear autocal. I have 8 different tunes for my truck. I have Tunes for size 22 rims and my 17 winter rims. I have a sport tcm tune that really moves the truck and it can make the 22 chirp in 1-2 shifts. Pretty cool when that happens, traction light goes off. I also have a tune for towing. You cant go wrong with a BB tune as it tunes made Directly based on your Trucks log files you send into them as where a General Tuner is so generic it wont do much of anything for you other than make you angry you spent all that money for something you cant tell the difference in.
Asking us on here if you should do a mod or not is like asking a room full of druggies if drugs are bad....
Haha, point taken. I guess I'm looking at it from the perspective of trying to find the best route to take, performance unit per dollar. If a burb is always going to be a burb, I'll skip it. But it sounds like even the lowboys can catch a boost with the right tweak, and at a reasonable price. SOOOoooO, glad I asked!
