First Diesel, first RAM, first dually, first new truck, first....

That sounds about right.
My truck is enroute in Mexico as of 0545hrs. this morning.

Is that North bound on a train or South bound on all four. Ha!Ha! Snoking

Link showing it's enroute from Mexico was posted @0545hrs. and with my luck it's probabbly headed south under it's own power on all four!

Just for my own education, and because I'm bored, I'm going to beat this horse. Every turbo charged engine has turbo lag. That's just how turbos work. When you first push on the go pedal, you have a normally aspirated Diesel engine until the turbo spins up. Since it's driven by exhaust gases, there is always a lag before the engine starts climbing the power curve. Don't like the delay? Replace your turbo charger with a super charger. Same idea, but the super charger is driven mechanically by the engine, so no lag. That's why drag cars always have super chargers. So why not always use a super charger? Because the super charger steals hp from the engine whereas the turbo charger doesn't. Is torque management making the lag worse? Maybe, but I doubt it. When you first push on the pedal, there isn't enough torque to even manage (until the turbo spins up), so there would be no reason to add a delay or whatever.

John, can we agree to disagree? My 2001.5 was setup for very little delay, and was very lively to drive. Of course the 2015 weights over a 1000 pounds more. Power levels on paper/dyno are not that much different. Snoking

As was mine.... But that was possible because the 24 valve trucks could fuel at low boost to reduce eliminate/lag but it would get a little smokey. The 4th gen trucks aren't allowed to smoke so at low boost, less fuel, more lag........Thank the EPA.....

True statement, why would anyone not agree to fact? "very little delay" and "reduce" is not "none"....

When we got my 93 it had lots of turbo lag. I switch to a waste gated turbo an it improved that greatly.

Our 2001.5 auto had the HY35 with very little lag, when I needed more cooling I installed a PDR35-12W that spooled similar to the HY35.

I will have to put up the boost gauge on the 15's EVIC and see when it starts building boost. Of course there is no knowing how much delay is in that meeting via the electronics in the truck.

It's just the truck!!!

The way they're set up, they are NOT going to do a 6 second 1/4 mile time run until you can change a bunch of stuff on your engine that will void the warranty.

My BD Throttle Sensitivity Booster has helped the turbo spool quicker. On 400% boost, it acts like a lamborghini.

But I don't use full (400%) boost unless I need to accelerate onto a freeway up a steep grade. Under stock throttle parameters, the truck has trouble accelerating its own weight from 20mph-50 mph because at these slower speeds the torque management inhibits acceleration.
Above 50 mph, the truck accelerates very quick even at stock throttle settings. No perceptible lag/torque management/dead pedal even at stock settings.

Some of the city ramps have tighter curves and require 30 mph cornering. Then when you hit the uphill part, torque management is a real drag.

While there will always be some, the difference between the 2nd gen and the 4th gen is the variable turbo. Bigger the turbo, the more lag. Variable turbo allows it to "act" small when spooling.
