2016 Ram/ bucking and chucking??

Shiner. What is the throttle valve?
I did not do the delete or tune myself. Actually the Ram dealer did the delete.
An EFI Live dealer did the latest tune which he says he will resolve.
I noted the pulsing right away running without trailer. Much more pronounced when towing.
Too sensitive throttle may be it.
But shifts are far to harsh for my liking.
Truck is crew/ 8 foot box.

Ha Ha SD. You may have a point.
I pull lots and am of the opinion that manufacturers often have flawed products but continue to pump them out regardless. IE the Ram tie rod/ gearbox set up prior to 09.

I share the driving in my trucks with other men who have similar trucks and every one will tell you that mine pull strong.
Also as I stated. My Ram dealer has deleated dozens of trucks. There must be a reason.

Tthe throttle valve is on the intake side right before the EGR valve. In normal operation it is suppose to open and shut to cause a vacuum in the intake so more EGR gas will be sucked in. If it is not unplugged then it will open and shut causing the engine ti shutter. This is just one reason for bucking.

How to unplug the throttle valve

Another reason may be torque converter shutter or your tuner needs to fine tune the fuel and air flow. This is why you are suppose to do a data log when first get a custom tune after doing a transmission learn drive cycle.

A tuner will generally send you a generic custom tune and you are suppose to run a 10 or so minute data log and send him the file along with any changes you would like to make. He will then go over the data log, make the changes you requested(if he can), and send a new file back to you to load into your Autocal. Most of the time the generic tune will be fine, but some trucks need a little more fuel mapping adjustment to make them right.

Also, the harsh shift is mainly due to your transmission "relearning" and is normal during this time until a few drive cycles. This also happens anytime the dealer re-flashes your truck.

Hope the EPA suits walk into your RAM dealer and slaps a large fine on them. FCA could pull their dealership for the violation of Federal laws.

Good luck at getting warranty service at any other dealer.

Ivbinconned, IM me if you have anymore questions and think I can help. Otherwise we might get more sierra club protesters, posts about voiding your warranty, and "why do you need more power" posts.

Maybe the truck needs a stack through the bed, too much exhaust pressure or what not,

Might help to fill in your PUBLIC signature !!! SPECS of your truck will help with the discussion!

If you have 3.42's it will want to tow in 5th at 60, depending on the weight you are towing.

Lol, right?
I’d say either throttle valve, trans re learn, or you just got what most people are wanting with a delete, more power and a trans tune, which is instant throttle response, killer power and crisp shifts. The opposite of factory, for the masses, tuning.
And yes, depending on your gears, 3.42 or 3.73, I wouldn’t even expect to use 6th except for flat roads, no head wind and over 70-75 mph. Remember 5th is now similar to previous models top gear. 6th is even deeper. Not a towing gear under a lot of conditions.

Thanks Shiner. I'll keep you posted. I find it amusing how by deleting and "tuneing" one can significly improve MPG resulting in less consumption of fuel is totally lost on those who worship government and all it imposes.

My truck has 3.42 gear ratio.
