@RexHoward, Your actuator is dying. Better get a City Diesel replacement on order as Geno's is end of March before they ship. Just did mine in Dec. Not to bad of a job. You'll have to drain antifreeze to do replacement. Look at the replacement install directions and ask questions. Did mine outside and basic hand tools. That's the exact way mine was acting, little boost and hardly any exhaust brake! Good luck with repairs.

 

And by the way, welcome to TDR! You'll find plenty of help and info. Everybody has either been there done that or knows where to point you.

 

You man want to contact RAM as they have done some extended warranties.

Here's another option. These guys reman them. Theyll send you a good one, and you send yours back after you install your reman. I used them last year to repair my dash cluster. They were great to deal with. If you can't wait until the end of March for one from City Diesel, this might be a good option.

Why would you want a reman? City Diesel has rebuilt for the ground up with far better components! Plus you don't need to rent a calibration tool or have to worry about returning a core! Still have a wait to get a unit from Circuit Board Medics. Why would you like to put on something that was a problem and had only the components that don't pass replaced! City looked to fix the issue not repair the issue! City gives your 2 years and 20k hour components along with a stronger drive motor. I would've been out a core charge due to stuck bolts that had to be cut and nicked the housing which states no damage to housing. All I had to do was bolt up, refill antifreeze and turn key.! JM2C. There's a reason that Genos will sell them.

 

Wow. Chill man. I was just offering a solution if he couldn’t wait until the end of the month. Circuit board medics are reputable just like City Diesel & Genos. They also offer overnight shipping. I had my EVIC cluster back in two days. We are all here to try and help. There is more than one way to do a repair, and more than one place to get parts.

 

I was pointing out that unless everything is new do to heat cycling on the electronics shorten their life. The factory unit has 4k hour electronics vs the 20k that City uses. I hate to have someone get a reman and crap out in short time. Not a fun job to do once let alone have to redo even if under warranty. A EVIC is a way different animal then actuator. Mine died just short of 5k hours on clock, so if all goes well with 20k hours parts, that'll be another 25 plus years till next time. When you loose actuator, you'll have less than 30hp EB power! Not fun if you're towing down a grade and need that help! Believe me, I looked at all possible options when mine started to fail. When you start to compare the fine print, City is the best choice short of replacing the whole turbo. No offense taken just pointing out the short falls and time shouldn't dictate you choice on a complicated repair.

 

I totally agree. I had an issue with mine and time was a factor. I didn’t have two weeks to wait on parts, so I did the “other” repair that got me back on the road & a more reliable truck.

 

Something else to consider is the electrical plug to the actuator. I put a rebuilt turbo on my truck and still had codes, no exhuast brake and low boost. When I wiggled, pushed or pulled on the connector things would act normal. If that is the issue Ram has a replacement connector with pigtails for it.

 

I just replaced my actuator with the city diesel one from Geno's. Actually showed up 2 weeks earlier than they stated. I had a P00AF code and my actual and desired VGT % Closed differed (see chart below) so it was obvious that the actuator was not performing. Lost my exhaust brake and had poor acceleration.


The City Diesel unit install was simple and works flawlessly.


They even provide a hex bit to get the bolt out behind the shock tower.
