Does the intake have to come off to do STC update?

[HAM_RADIO_MAN]

I am getting ready to do my EGR delete and STC update. I know I need to pull the turbo and the directions on the EGR delete says there is no need to remove the intake so can I do the STC update with out pulling it off as well? I think I am just looking at pulling the Turbo and a bunch of hoses and the alternator. Am I on the right tack with that idea? My oil cooler is in great condition so thats why only the EGR delete.

You don't need to pull the intake to do the STC update, you will have to remove the passenger side intake bolts and loosen the drivers side intake bolts to gain enough room to remove the EGR cooler. I would recommend removing the intake and replacing the intake gaskets and the large coolant passage o-ring between the intake and front cover. you would also want to replace the oil filter base o-ring and get a fuel filter housing o-ring kit to re seal all of the fuel lines at the housing. you don't have to do it this way, but if you're loosening the intake bolts and don't replace gaskets/ o- rings you could run a risk of developing a leak. Hope this helps

Thanks, Now I am looking for an inexpensive EGR delte kit. I want on of the ones that uses the freeze plug in the up pipe and the bypass pipe. Any ideas on that.

Personally I am not a big fan, the up-pipe has a scoop in it to direct more exhaust gasses towards the EGR cooler, which works good for promoting EGR flow. The issue is that when you install a blocker plate you are only gaining part of the benefits, you stop the heat from entering the EGR cooler, reducing coolant and oil temps, but you also are creating turbulence in the passenger up pipe. with that added turbulence you may not gain all the benefits of increased fuel mileage from the EGR delete. Also eventually all of that heat being directed to the blocker plate could cause the plate to fail although I have not heard of that happening. You are also going to want some tuning to disable the EGR system and to shut off the monitor to prevent the CEL from being triggered.

I have unplugged my EGR valve after cleaning it and I don't have any codes or CEL. I was hoping that without flow through the cooler it would be cooler and less prone to failure untill I got rid of it. I have not had any turbo or fan clutch problems that you can see when unpluging the egr. I think I have one of the older flashes for the PCM that work good.

I have seen it done both ways and pulling the intake is the right way to do it. Fuel filter o rings great suggestion!! One thing on the STC fitting replacement, make sure when your reinstalling the pump that all bolts especially the link to the branch tube can turn all the way in by hand then tourqe. That way you know its lined up correctly.

Without a good scan tool that can read actual fan RPM, you'll never know for sure if your effected. There may be a time that your gonna need full fan RPM function and won't have it. It's your call, either take a chance with exhaust flow thru the EGR cooler or possibly running the motor hot from lack of proper fan operation.

once I do the delete, I will leave the egr valve in the hole as a dummy and pluged in.

it just depends on the truck, mine an 05 as well, didnt throw a code after my egr delete on the stock tune but i run matts srl custom tune. 03-04 mostly dont throw codes, 05's are hit or miss and for the 06-07 they usually always throw a code for egr deletes

I have one of those types. I actually prefer it due to the fact that you retain the OEM flex in the up-pipe

ALSO because my truck is an 06 the original up-pipe did have a scoop(05-07)

if you install a late 04 MY uppipe it will be the correct size and not have a scoop. If you would like to install one I can get you the part number. That's the direction I went
