Lucian,
It's the same on either.
If you have any questions in the future, cal either Mark or Piers at
Piers Diesel-604-888-4159.
They all drive these trucks & know them inside out. One of them could tell you exactly what is entailed to bypass the TPS but it's literally a 10 minute job for any electrical shop & you certainly don't have to install the lever...you could keep the dash switch but it's a bit of a pain reaching for it. Lots of guys install foot operated switches like a dimmer as well.
It's best for your engine to only use your OD when you're on the highway anyways.
Contrary to what most people believe, a Cummins engine should never be run under 2000 rpms & NEVER tow under 2200+.
Cummins themselves consider anything under 1700 luging the engine & a real bad no no, so you'll find keeping in the right RPM range much easier with OD off.
Both my trucks got best fuel economy at 2200...considerably worse at 1800.
Take Care!
