I'm considering adding the TVS1900 or the TVS2300 to my H2.

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!   |
I think there's a 'potential' for some minimal fuel savings...but as you increase the performance the 'potential' of gettin' up in the gas also increases. Those two tend to cancel each other out...lol.
6.2 and the 6L80 are definitely a more appropriate combination for a truck this size (IMO) since they didn't wanna give us a Duramax/Allison out the door.
Good luck...
