Adjusted the high speed gov screw 3 turns and unloaded neutral RPM went from 2300 to 2600.

Dynomax race bullet only cuts 2-4dB at the best according to Dynomax.

Are we sure its a T4 exhaust flange?

Thanks for the info, can you take a picture of the casting marks?

Nice. So it's a 54mm compressor. Now I'm curious if the a/r is cast on the housings like modern turbos

Does anyone have a unit off the truck right now?

Only revs to 2300 in neutral

Ok lets discuss known factual info on the specs of the C/D turbos in here. I want to know the following Compressor MM size Turbine MM size Compressor A/R housing size Turbine A/R housing size Downpipe flange OD/ID Compressor Map

Pedal stop is no where near the end range of the pedal, should I adjust it up to make it work?

Drove it off road Sunday 3rd gear I can do 2450 RPM, 4th and 5th gear it is 2200-2300 Max. Re bleed fuel liine prior to this trip as well. Gonna inspect it today and see if any lines are kinked and if the pedal stop is an issue. I did notice the truck will now do 41 mph in 4th gear when...

I have repeatedly stated I want to find the info on the details of the turbochargers, simply saying is bigger then enough doesnt cut it for me. That is relevant to the differences in the motors and cannot be ignored.

All fuels have a Stoichiometry ratio so you are flat wrong.

Turbos simply move air and you need a certain amount of fuel to meet the proper fuel ratio in response which makes power. Upping the fuel rail pressure and upping the boost equal more power. Now the factory turbo might be close to out of steam. Need those stats. What mm is the turbine and...

Boost will make more air which allows more fuel to be burned. Knowing the exact lb/min of airflow at a given PR will let us be able to plot if the turbos are maxed out to begin with or not. I have a hunch that a T54E would probably make one of these trucks scream. Also upgrading the fuel lines...

Vision X LEDs work on 5-50v, that is what I am going to install.

I still want to see specs on the turbos as that will really settle this. Has anyone ran an aftermarket turbo on these?

What is the stock vs stock boost difference. The fact the lds runs a larger turbo should indicate the power difference alone. Any one have specs on the turbos or a compressor island maps?

The engine quiets as it reaches 2200-2300 RPM, almost as if it is defueling at that point like from a governor.

I'm gonna check the lines for kinks and then rebleed then check the adjustment of the pedal stop and go from there. I'll report back tomorrow

I'm reading the tm that was linked. But unless that was Posted how would I know which tm to read. **** some have 1500 pages. It's nice to know that some people are more focused on helping a member rather then if they spent time using the search button which guess what I did.
