In my 07 it tapped out at 117mph for like 3 miles. In my 05 Denali i got that to 134mph.

Sounds like the lowered the limit over the years...

Because you only get one telephone call from jail .

They'll give you more than one... as long as they person calling will accept collect calls.

theres a bit of difference in the ppv its goverened at 149mph and it has z rated tires wich are 140+ plus also has larger rotors larger alternator a second battery for the communications eqiupment thats required to stayon while the vehicle is off
lower suspension
a ssv is basically the same as a ppv except its 4x4 and governed to only 120mph

Having 2 batteries is a wonderful thing, Everything cop related ( Lights, radio, computer, RADAR, camera system, wifi/cell receiver etc) is wired to the second battery. When I had a CVPI, I routinely had to jump start the damn thing

They may be rated to top out at 139 or wherever but mine wont get much above 125, too much stuff added to the initial weight.
