Best 2.5" turbo?

I've had a Danville charger for over two years. It just rips. The customer service is top notch. And he's only made them better since I put mine on
Dts is a awesome choice. Look at his workstock truck. It does awesone with his stock appearing charger.
theres a duramax down around Kentucky running an ED turbo that seems pretty tuff when it makes a pass
There is about a 150-200hp difference between 2.5 stock appearing and ITPA/bob 2.5 class so you need to be more specific with what you are looking for. I have stock appearing guys in the 750hp range, best 2.5 vgt power was 720hp, my custom billet S463 in the 850+hp range.:thumb:
the points leader in the b.o.b. runs one of yours. the guy hangs right in there with the heavy hitters even though he doesn't have duals or even dual fuelers!:thumb:
Hell yes you could Ben! You could also use the big 2.5 turbo since you are still rocking the true 2.5 S4! would be 100hp increase for you!:thumb:
Hey Mark, what would your 463 do for my pile?? think it would finally finish me off????

Chase Fleece sure is looking forward to getting to those rule meetings this winter and getting the "big 2.5" stuff out of it, and getting the clarification established so that it remains a True 2.5" class and as an intermediate class between Work Stock (Stock Appearing) and 2.6". With the way its headed now, we are only a water to air and weight box shy of 2.6".
The lack of rule enforcement, and teching each pull has allowed the class to get out of hand in both Indiana and Kentucky, which is a shame.
