What in the world is on there Tahoe

[Clean07Burb]

I was lead to believe that the PPVs have a different tune compared to civilian models.

Is there somewhere that states this fact? I need this info for my own sanity.

I had a "tune" done to my 07 PPV and the shop never saved my tune.
No dealer around me has proven to know what I'm talking about when I ask for a re-flash and I'm having a hard time trusting most if not all shops around me. If this is true, I can go to one person I know to have him re-flash a newer Tahoe's tune in mine. He can save that tune, use it as a baseline and we can go from there for further tuning.
Then I'd be happy

Even if the PPV's had a more aggressive tune from the factory, an in-person tune from a reputable tuner such as Justin of Black Bear Performance will still always be better. BTW, why didn't your tuner save your stock tune?

Yes, you are correct an in person tune is better.
I had another local shop do a road/dyno tune.
I'd be a very happy camper with my factory though, with my DOD disabled of course.

That's the million dollar question, hah. Incompetence I presume.

okay police vehicles need to be capable of much much higher top speeds and better handling so having a low gear ratio like a 4.10 would be defeating the purpose of the PPV tahoe
the main differences in the 2015 PPV or police persuit vehicle
the 5.3 liter ecomumbo jumbo engine is now 355 hp wich has a fuel cutoff at 139mph
and AC cutoff at wide open throttle the earlier 5.3 liters only had 320 hp
dual isolated batterys
170 amp alternator
3.08 rear locking diff old tahoes only had a 3.73
beefier cooling system suspension and electrical system
they also run V rated tires wich are good up to 149 mph

I'm an officer in PA....

You must be from the western part of the state, where we still have a bit of common sense.

Gimme a liter of cola.

Does that look like spit to you?

My gutless throttle body 350 acted the same way with 4.56 gears

Just checked 2010 Tahoe to a PPV 2010 and the engine and transmission tune are exactly the same.

Sent from my fone.

Is everything the same? Before Justin tuned my truck it was limited to 99 MPH, etc. I can't imagine these speed limiters and such would also be included on a PPV. I wouldn't want a police vehicle that was limited to 99 MPH. Lol

I am also curious.
I thought I had read somewhere that they reach up to 130+mph.

Speed limiter is not located in ECM/TCM in that year. It is attached to Stability or something along those lines.
