I’m curious how much of an impact the turbine housing has on spool up and peak boost numbers. On a 6.7 and stock fuel will an S467 with a .90 reach a higher boost pressure at WOT than a 1.0 housing? I am curious because right now using a 1.0 A/R on stock fuel WOT boost is only about 22...

Maybe this is normal but I want to make sure. I have noticed a clunk somewhere in the driveline when disengaging cruise or when abruptly getting on or off the accelerator. It does not make the clunk when coming to a stop or when accelerating from a stop. I started to notice it after a new tune...

I’m looking for options for ezlynk tunes with 68rfe TCM tunes. I am hoping someone has experience with Firepunk tunes on a 4th gen and can give a quick review. I’ve narrowed it down to CTT or Firepunk.

I have been trying to find a whining sound that seems to be coming from near the alternator on my 2014. It starts at about 1100 rpm and is there on acceleration and when revving in park. When under the truck it can be herd but is very faint. With my head under the hood it is most noticeable near...

I’m suspecting a bad fan clutch on my 2014. The AC compressor seems to cycle on and off a lot and I don’t ever hear the fan engage and get louder. The fan will spin with engine off but has a good bit of resistance. With the engine on I can stop the fan with my hand. I turned the AC on max and...

I am having a bit of trouble on my 2014 2500 with a squishy brake pedal after the engine is shut down. I decided I would flush the old fluid and after the flush the pedal will sink to the floor when the engine is not running. Brakes work normal with the engine running. So far I have bled the...

Last night on an evening drive the wife heard a strange clicking coming from the passenger side front wheel area. Almost like a rock stuck in the tire because it would change frequency with the speed of the tire. After getting home and investigating I found the front axle u-joint has a good...

There is a sound that is almost like baseball cards in bike spokes coming from what seems to be the turbo on my pickup. The sound only happens when in gear and it starts to build boost. Light acceleration does not produce the sound and when in park or neutral it does not happen. Does this...

I have a 2003 with the apps on the block above the cp3. I want to move it so I'm looking for a dual cp3 kit relocation bracket. Thanks Sent from my iPhone using Tapatalk

I am planning to replace the transfer case slip yoke bushing and output seal because I am putting on a new slip yoke. From what I understand all I need to do is remove the rear extension housing, push out the old bushing, put the new bushing in, and then put on the new output seal. Does that...

I am looking for shock tower mounting rings for a 2003 2500. I am wanting to remove a leveling kit and know I need the rings but I'm unsure if I need new isolators as well. Thanks, David

I am trying to change my exhaust to a 5inch and I bought a 2nd gen downpipe with a hx40 flange that is smaller than the flange on my turbo. The flange is flat like a hx40 but measures 4 and 3/8 inch. The previous owner had a make shift down pipe set up on to fit the 2nd gen manifold an they used...

I have a 64/68 with a 13cm gated exhaust housing. It is an engineered diesel turbo with a spring actuated gate on the exhaust housing. During a hard pull, the highest boost I have been able to get is 29 psi. Is this normal for this size turbo?

I took it off my 03 cummins. This one will work on 2003-04 cummins. I have everything for it including egt probe. It works great I just didn't want it stacked with my smarty tuning so I took it off. Thanks, David

I replaced a fuel filter delete block with a stock filter housing and when I removed the feed line from my fass pump to the cp3 it did not drain a lot of fuel like I assumed it would. I assumed the line would be full of fuel. Is the fuel somehow draining from this feed line back to the tank...

With light acceleration I am hearing a clank noise from somewhere in the driveline. It only happens with light acceleration and between the 2nd and 3rd gear shift. With heavier acceleration it doesn't make the noise. My transmission is a 48re that was recently built. I'm not sure if some noise...

I am looking for the fuel filter housing. Currently have a fuel bowl delete block but want to go back to the stock filter. Thanks.

With it starting to get colder (today was 24 deg) I have noticed a white haze from the exhaust when the engine is cold. It isn't big clouds of smoke just a little to the point where you have to move around to see it right. It is a little easier to see when accelerating. Once it heats up I don't...

The turbo oil drain on my pickup is leaking a little and I'm looking for replacements. Is there one that is most commonly used? I found source automotive and vulcan diesel sell one for second gen swaps and I have read about guys just buying the turbo fitting and building their own. Any advice is...

Hello everyone, A little over a year ago I joined the website and posted in the introduction section but didn't actually introduce myself. I have posted a little, but I mostly just read and try to learn as much as I can. I am new to diesel and have very little experience so most of the time...
