Unfortunately if you have the 340HP ISB, there's a good chance you have the Allison 2500 transmission with it and if that's the case, your engine's already producing the max torque the tranny can handle.

That was my first thought, too. Be sure the Allison can handle the extra hp/torque.

I think the folks at Mercedes/Cummins know what is optimal for the ISB,
any after market modifications are likely to cause issues over time.
