I don't think he wants to modify emissions, sounds like he just wants it turned up a bit.

 

Take it to an engine shop for the type of engine it has in it, such as Detroit or Cummins and have them upload the software for the higher horsepower rating. It costs a few hundred dollars but it's worth it if the power is turned down. Just make sure it doesn't breach your contract with Swift before you do it.

 

Do you own this truck? If not I would wait in till you own it.

 

Exactly what is it you expect to achieve ... yeah you can turn up the power and go upgrade faster ... but all you accomplish is wasting fuel ... you making that much that you can afford to burn some dollars just so you can impress other drivers with how fast you can go up hill?

 

Check your lease probably has a section about modification of any part of the truck.Usually if caught they will cancel your lease as its not really your truck and could void any warranty

 

It will cause more soot build up due to more fuel burning . Cause more freq regens . really not worth it .

 

it takes a while to find sweet spot when driving alot of variables wgt etc. My friend drives a t680 10 sp with 3.25 geared rearend avg 8.3 + he keeps it between green shift point on the tach. with 200gal tanks he get awesome miles almost 1600 mi

 

Some times its better to carry more speed in the bottom of hill, so you get a better start at the next one.
