Gotta Ask--Tuner

[WilliamBos]

I would avoid it - even if they remove the tuner it leaves a mark on the ECM. When the GM dealer connects it will show and powertrain will be voided.

Keep looking, with the new HD on the way there should be some decent rebates on the current trucks.

Lightly looking at a 2017 Chevy LTZ 2500 Duramax. Since it has aftermarket tail lights (why?) and some other stuff, I asked if it had a tuner. Dealer (honestly) said yes for MPG (What all people say)...Anyway..It has 21k on it and I certainly don't want to have a voided 100k warranty due to it having been tuned .

I think the warranty is shot--Opinions?

They are asking market for it, so no great deal although there might be some room on it--The truck is mint though. Thinking I should look elsewhere--Not sure I even need/want a diesel anyway since the 6.0 and the 6.6 have similar towing capacity and that's really what I'm after.

Again, with the 2017 L5P, the "tuner" is inline after the ECM. Zero foot print to the ECM as it isn't actually touching it like traditionally done in the past. Doesn't mean I wouldn't keep looking for something - like the ones I posted above.

Thanks for all of the feedback--I passed on that truck--Too many unknowns beyond the tuner..Fuel tank in the bed, aftermarket tail lights etc. Nice looking truck, no visible damage or signs of abuse but too risky in my opinion.
