I was thinking the same thing. Maybe someone can shed some light. Or point to a link

So the flash counter... it just counts how many times it's been flashed? I am the damn GM of a dealership, if I want to use the GM approved equipment that my Gm shop owns to reflash my truck 300 times and not change a thing, who's to say I shouldn't do that? That would run up my flash counter wouldn't it? I have access to all of the equipment in my shop and a reasonable understanding to run it all. So what good is a flash counter if I never touch my truck with an aftermarket tuner but fiddle with it every weekend?

My point being, I'd argue it if my DSM says my truck was reflashed with anything non-authorized if they can't find it because it was put back to stock.

Any thoughts on this?

The flash counter is for GM to keep track of how many times it was changed/flashed, that's obvious.

The thing with that is, if the dealership does not have any record of flashing the truck, GM then knows it was someone other than a GM approved shop that flashed it or changed something. GM will argue that their people did not do it because there is no record and that some sort of aftermarket modifications were done at some point.

I am one of those who knows a warranty can not legally be void just because of an aftermarket modification but certain dealerships will lie to you and tell you otherwise. There are laws that protect customers from this type of nonsense but there are people who will try and argue otherwise. There are several topics with that argument in it even though the exact laws that protect us were cited and posted, they believe what they want.

GM doesn't want anybody that is not approved by them to do any work or modifications to these vehicles, it's silly but that's their thing. I guess they believe they have been replacing engines/transmissions on their own dime because of other peoples mistakes for far too long.

Is there a good thread where folks are comparing notes on what they are running in a diablo tuner?

I just got mine today and am unsure of what to choose for some of the settings.

I put in the diablo tune with dod off, tm off, 8% throttle boost, and left pretty much everything else alone.

What should I use for throttle boost and why?

After a lot of reading on different sites, forums, and posts this is what I've come up with as a good setup with a balance between performance, driveability, and well lower risk of damage you could say. Of course this is just my opinion and I'm no expert but this is what seems to work best for me and what I feel most comfortable with.

I use the Diablo (91/flex) tune.

I've settled on keeping DOD on just for the 1mpg I lost with it off. This one really is just preference I think whether you want a V8 all the time or not. I don't have issues in V4 mode or coming out of V4 to V8 when I get on the gas. If I don't want V4 mode I just put it in M5. I've not ready anything in regards to oil consumption with the new ecotechs so I'm banking on GM having fixed that issue.

I would recommend putting your throttle boost back to 0. Reason is there have been a number of complaints about the tranny shifting/banging hard on shifts at WOT only. On 1-2 shifts the most I think. I've experienced this myself. It kind of feels like the tranny is going to break when it happens. From what I've heard from DiabloSport it has to do with the throttle boost. If you post on their forum they have actually custom tweaked this in the tunes for a number of people who have reported it. I got one from them last week but have not had a chance to try it yet as the roads have been snowy in my area.

Also in the Diablo stock tune they have already dialed engine torque management way back (something we as end uses cannot adjust). The TM for the tranny is separate and it's only on or off and I would recommended leaving it turned on in the TCM tranny tune. From what I've read it's much safer on these 6 speed trannys for it to have some TM applied during shifts and I don't want to break mine. I've settled on the hard TCM shift vs the firm one. Just feels a little nicer to me.

Hope this helps.

I have a Diablo Intune I2030 for sale. I sold my 2014 Silverado that I had it on. I returned the truck to stock so the tuner is unlocked and ready to use. I bought it directly from Diablo December 2016. $200.00

My Camaro has a killer Livernois tune and I want one for my truck (it has a 6.2 as well) but I will wait until the warranty is up. It's a long hard wait but worth it to me. Those who don't wait I totally get it and don't blame you one bit. As for the raging tire size/dealer fix debate...I'm glad your dealer can help and not sure why anyone would care and argue so much against the fact. Too many people feel the need to be experts on everything.
