$800 Budget to make my 6 liter reliable as possible, what should be on my list?

[2004F250XLT]

I have alot of miles on my truck. But its starting to show some age and i want to get better fuel mileage. Performance wise all i have is an exhaust and blue spring upgrade. With 800 dollars to spend, what do i need to get to make my 6 liter more reliable, better running, and better fuel mileage. Im putting aside all my exterior accessory wants instead to make my engine perform better. So what should be on my list? Thanks

EGR delete for sure.

1. gauges
2. coolant flush w/proper chemicals and fill with ELC
3. colant filter
4. egr cooler gone

1-3 should be less than 800. Bet all 4 would be about 1000.

So a custom tune is not necesary yet? I mean my truck seems to run perfect with the factory tune. Egr delete kit is on top of the list, I cant re use the stock oil cooler though? Do i have to leave it on for the flush, then replace it after the system is flushed and egr delete kit is installed? Thanks alot guys

Imo guages should come before any performance mod, after all what is the poing of spending your money on progrograms only to find out there is 30* difference between your ect and eot

If you have to do the oil cooler ,be sure to do the flushes before removing the oil cooler,you can do the egr delete when replacing the oil cooler.

before you go changing out the oil cooler get a set of guages or CTS to see how its doing, and you wont be changing that out or removing it for the EGR delete

ya i definetly want the edge cts, but might settle on a bully dog watchdog. But can i still use my oil cooler after doing a flush and right before installing the egr delete kit? My oil cooler is doing its job now, but im just wondering if it is a must that it has to be replaced when doing a flush/egr delete, because ive heard that it is, so thats why im considering one of those sinister solution kits with the egr delete, oil cooler and intake gaskets.
