Just curious why? I run the X2 with the TNT on my 04.5 and like it alot. Is there something I should know about this stack?

 

Watch out because of all the timing...watch out. Head gaskets blow because of 2 things...excessive pressure and too much timing! Your first priority need to be the studs and springs.

 

^^^^ exactly... i dont stack with it anymore because of high boost and too much timing... right now my quad is a fancy rail pressure gauge..

 

Umm.....HELLO!!! Has anyone bothered to notice the truck still has a stock turbo? You should not be stacking anything. You can't even take full advantage of the Smarty, why would you need/want to stack?

 

That's why I asked. I see a lot of people stacking on here and it doesn't appear that they're all ugrading (or have upgraded) their turbos. So there's no benefit to stacking anything without upgrading the turbo and, apparently, other things?

 

I ran a smarty/quad stack on my stock turbo for a long time. Ran a 14.15 with the stack...Then I ditched the Quad, tuned the Smarty and ran high 13's. Added a turbo and ran mid/low 13's. Added 30" tires instead of 35's and a TST and ran a 12.76.....The difference when DYNO'ing was 27 hp with the tst added. I picked up another 30 hp by dropping the tire size.

 

Well I'm not dropping the tire size . . . at least not until these mortage payments I've got on right now wear out, HA. I don't think my truck would look right now 30" tires and pocket flares either I'm sure there would be a decent fuel economy increase with dropping 5" on tires as well.
