I'll check in to this but honestly I don't think so. I think they are all built to CA emission standards

Federal emissions override is probably for Mexico and everywhere else. CA emissions is more than likely just for US and Canada/ Eastern Europe.

Sorry guys, its nothing special.

Literally all it is is the DTC reporting tables are slightly modified for which codes turn on a check engine light, and how many times a diagnostic must fail before setting a code.

Its not a "less emissions" truck. Its not a mexico truck (they dont even sell duramax's in mexico, or europe for that matter lol). Its not a special government truck. Its not an EMS truck.

Good to know, I'm ok with nothing special as long as it's not a choked up version. Thanks Ben

Nope, not as far as I know....

Otherwise someone would have started selling factory mexico/LAAM "delete" tunes a long time ago.

Thats how people are deleting the 2017 Powerstrokes...some tuner got ahold of the Ford mexican/LAAM ECM tune...and now they're selling it as their own for a ton of money (real slick move, assholes).

Like the L5P ECM, the 2017+ Ford ECM requires tune files to be RSA-signed by the manufacturer before the ECM will accept it. So what that means is you can only flash in files that are made by Ford (or GM).

Thats why the 2017 ford emissions delete "tunes" have no extra power added, just deleted emissions. Because its a 100% factory Ford file, it has the proper signature on it, so the ECM has no problem accepting it.

But its so hack...first of all, total dick move making tons of money off of something that you literally have *zero* time/effort into making.

Second of all, ive heard some people say it actually runs worse and is a little less responsive than the regular US/Canada tune.

And thirdly, ive heard of multiple people having issues with check engine lights etc, because of slightly different hardware/piping on the actual Mexican/LAAM trucks....so when flashed with the Mexican tune, sure it deletes emissions, but the ECM also sees some other things (US/canada hard parts) amiss...and can set codes. And NO you cant "shut the codes off" because, again, the ECM will ONLY accept a factory-authorized file.

The only way the aftermarket is going to be able to get modified tunes into an L5P is if someone on the inside at GM Powertrain has sticky fingers and wants to make a fast couple of bucks.

Its not about being a smart talented "hacker" anymore. Its not about truly reverse engineering stuff the hard way. This shit is so complex today and the ECM's are so smart that it would take probably 100+ years to actually brute-force the algorithm.

Nowadays its purely just who has a big enough checkbook, and who is lucky/clever enough find connections at GM.

So if/when someone does publicly release L5P tuning, dont congratulate them, dont hail them as some hacker genius sent from tuning god heaven, and dont think for a second they did it "the hard way/from scratch". But do be sure to thank them for dropping the initial cash investment on stolen information!!

Back to the days of water/Meth, crack pipes and stacking foolers I guess for the L5P.
