Temps look good! What should come next?

[JWhelan2787]

Just got my DashBoss in the mail yesterday and after hooking it up and driving in close to 90 degree weather today, I have to say that I am pleasantly surprised that everything looks good! Only a 4* delta between EOT and ECT with stock EGR cooler! Tranny temp looks good and FICM is steady 49-50 volts. Having said all that, what do y'all think I should do next? The truck is bone stock minus the blue fuel spring and monitoring system. I don't tow anything and would LOVE better MPG (I'm lucky to avg 13). Thoughts?

Dump that EGR cooler before it pukes....

Theirs plenty you can do. To start off maybe an 4 or 5 inch turbo back exhaust, then a good custom tune and you'll be good to go. I wouldn't mess with deleting the EGR until it starts to get you trouble. I've heard plenty of stores of guys flushing their system with perfectly good EGR Coolers and ending up clogging them up. Just wait till it fails, because it will. Theirs always plenty of things to do, it never ends.$.$.$.$ lol

personally i would delete the egr first. this is a huge weak point, then flush out that old coolant (rebuild cooler as needed). then coolant filter. then exhaust chip etc

Coolant filter for 5000 miles then fleetguard flush. Then egr delete.

yeah, thats a good idea to get that coolant filter on there first, then flush then do the delete (most likely after the flush your cooler will plug).

your going about it right, monitor first then proceed.

it would be best to get the coolant system healthy first and delete that EGR before you start chipping.

Them EGR coolers are no good and have been known to leak coolant into the intake system which in turn creates havoc. lifting heads, overpressurizing the coolant system and putting moisture into the turbo which rusts the vanes and makes them stick.

In your first sentence you mentioned that after I do the flush, my cooler will likely plug. Which cooler are you referring to and why would it plug?

He is referring to your oil cooler. After doing a coolant flush you loosen a lot of crap in the system that will most likely get lodged in the oil cooler plugging it up. This is why you should always be prepared to do an oil cooler replacement after a flush.

[JWhelan2787]

Not to sound like an idiot but wouldn't the repeated flushes with hose water remove all of the gunk so it wasn't still present when new coolant is added?
Also, how commonly does this occur?

Dont worry about not knowing something I was the same way when I first got my truck, everyone on this site is happy to help someone out if they dont know something.

Even though your flushing out all the coolant as you are doing the flushes it still has to go through the oil cooler so some of the crap your flushing out gets caught in there and wont come out. Now this doesnt always happen but like I said I would be prepared to do the oil cooler swap in the case that it does make your deltas spread more. Another thing, when you do the flush its ok to flush the first couple of times with regular water but before you are ready to put the new coolant in you should completely flush it a couple times with distilled water. The reason for that is cause when you use regular tap water in has minerals and stuff in it that will build up on the inside of your engine and oil cooler. Oh and make sure you dont put the same Ford Gold Coolant back in there. Switch to an CAT EC-1 rated coolant such as CAT ELC.
