F350 Super Duty vs 3500 Denali vs The Ike Pulling 30k lbs

It is not so much as a "fix" for a turbo, but rather making it perform better in a certain situations, however, this may take away from how it performs in other situations. Making it better for lower altitudes may decrease its performance for higher altitudes. Making it spool quicker at lower rpm may reduce top end performance. Having an air to water to air intercooler may reduce lag and improve off the line performance, but it will reduce sustained performance especially in hotter temps. It is a give and take and I doubt GM or any manufacturer designs their turbos just to post the best possible time on the Ike. you also have to throw emissions into the mix.

This is likely the reason why Ford has went through four different turbos on the 6.7L since 2011.
