Get your traction settled down and i bet your truck runs a low 14 , as is.
that would be about right for the weight and type of truck you have.
sounds like it's a fun sleeper!
The stock escalades with 6.2L are decent, but they aren't that fast. don't get me wrong, they move out pretty well, but like anything, they need a power adder, haha.
mine has been running 15.0-15.1 in this heat, no winter times yet.
i know for a fact it'll go 145mph tho, lol.
btw, it's an ext, heavy as a tank.
