How much power would you guys say with a 6637, TW tune, 3" DP to stacks and stage 1's?

[Matt P]

Id say 330 or so, I made 300 with those mods on a street tune, so extreme would probably be a little more

Most I've seen posted was 340HP.

Really? Wow I guess I expected higher numbers then that. What about torque numbers?

[Matt P]

You wont see that high of numbers with just stage 1s and custom tunes. As for torque Id say around 585-600

Boy its really gonna take some money to get into cummins territory I see.

Yeah, it'll take some money. Nobody said that modding was cheap. As for injectors, if you want more power, then you need to look beyond stage 1's. Stage 1's are just a step up from stock really. Stage 2's and stage 3's are where the "monster" power is at, and if you're heading down that road, then you've got a lot of other modding to do first. (head studs, cradle, etc.)
