I try to look through the old threads before asking questions already answered 10000000 times
I'm considering adding the TVS1900 or the TVS2300 to my H2. The shop that i'm looking at using has done many of both to the corvettes and escalades (can't remember if he said he's done a hummer, but escalade is the same drive train). Said those guys have been BEATING the Crap outta theirs and no tranny problems at all
the difference between the two is one is 7 PSI and the other is 10 PSI.
I am curious if the gas consumption will be worse, but really with this SUV can't see it getting worse LOL ... I have found the 6.2 with that 6 speed tranny is much better on gas then the 6.0 with 4 speed.. I owned a 2003 and now the 2008, well worth the change!
