Hi, new member here and a 1st time diesel owner. I read up on the specs and all for a 2018 3500 I was looking at, from out of province and I took it for a test drive. Holy smoke did that thing haul! Seemed to pull just as hard in a tall gear as in low. I noticed too that the throttle seemed to have a stepped feel to it, an easy range and if pushed further it got a bit stiffer, when it really put out the ponies. (anyone recognize that?) I thought "Wow, these L5P's are really something!", me believing I had experienced the stock 445 HP/910 Ft Lbs torque they talk about.

While I was dicking around somebody else bought that one and I ended up buying a 2018 High Country.
Thing is, this truck doesn't go nearly as well as the first one! That truck went like the proverbial raped ape. This leads me to suspect that the one I tested was modified to some degree by its former owner. Yeah I slap my forehead too. :)
My question is, what do the wise experienced 6.6 gurus here think that 1st truck might have had done to it?
Thanks.

Could've very well been tuned. If it wasn't louder, it was probably not deleted. It might've had intact emissions tuning. I seriously doubt that someone would sell a 2018 with emissions intact tuning and not mention it, though.

Was this test drive done at a dealer? I thought neighbors to the north were even stricter than us when it came to selling deleted trucks.

Hard to say. The seat of the pants gauge is hard to convey over the internet.

The truck was at a local dealership lot but they get their used stock from trade in and auctions, and aside from walk around inspection for dents and rust their incoming trucks don't get an inspection until point of sale where a mechanic goes over it for safety compliance (brake pads etc.) so a truck from another province could well have slipped in with undisclosed modifications. Since the trucks are drive-by-wire I thought this might explain the two-step throttle pedal feel, as maybe a feature of some tuner. My 2018 isn't like that.
It did not seem any louder than any other diesel truck, it just went like a bat out of hell when you got it on.

Yes a Banks pedal monster would be my bet.

It most certainly could depending on the level the pedal monster is set to.
As mentioned previously, it is a wonderful little mod to fix the "dead pedal". That along with the iDash are an excellent choice for starting out with modifying the truck if you want to go down that path.

Ah congrats, but did you get the pedal monster? The Derringer will not fix the dead pedal feeling.
Trust me, I wish I bought the pedal monster first.
Actually I haven't been bothered by any dead pedal feel, I only mentioned the throttle pedal by way of describing what appeared to be a '2 stage' feel to the pedal, in the hope that would trigger someone to say "Oh, that's what the * mod does!" and thus help me identify what it was that made that truck go like stink and thus enable me to do whatever that truck had, to my truck. :)
