Only thing is we are discussing a 6.7L ISB in a MH.
Your link is for the ISB is in a Pickup.
A Pickup has less torque because of the limited power the transmission can take in them.
The ISB torque in a MH with the 5 speed Allison(620 lb ft) does have less toque then the 660 to 750 lb ft 6.7L put in a Allison 6 speed.
The '08' Discovery had the 6.7L 350 HP engine in it.
I added the Banks kit to mine not because it wasn't adequate going anyplace.
I'm a old drag racer from the early 60's and was always adding more HP.
I only added it after owning the D 3 years and I had some extra $$$$ to play with.
The extra turbo boost from OEM 23-24 PSI to 33-34 PSI is not needed or used on most travel days. But nice to have.
The OEM ISB had no problem driving anywhere in CO. before the add on.
