i was thinking of doing a kitty delete and 4 inch turbo back first. I'm mixed on the egr cause i have read in this forum trhat the egr delete actually increases slightly the fuel consumption.
To go with a tune would mean studs for insurance right?

Don't spend lots of $$ searching for mileage. You will be disappointed. The other added benefits such as power and driveability are definitely worth the $$, but the mileage increases will be minimal at best.

Ive never heard of doing the EGR delete lowering fuel mileage?? If it does anything for power or fuel mileage, it would help it!
If your state doesnt have inspections GET RID OF IT! Because when the system does fail (Which it will) you will be looking at some $$$$.


As far as the tuner goes, you will get mixed reviews here. It all depends on how much self control you have. Some guys are reserved, use the chip for better MPG and slight increase in power, Others feel how MUCH power they now have,think they have a race truck and the pedal stays on the floorboard 90% of the time. With studs thats fine, but with TTYbolts, prepare to blow the gaskets.

I would start with the basics.....
Run a good fuel additive (Cetane booster)
Change both fuel filters, and oil filter

1) EDGE CTS MONITOR or another monitor device
2) EGR delete
3) 4" turbo back exhaust
4) Upgraded fuel pressure spring from ford
5) SCT with custom tunes from one of the tuners of your choice.

Adding a coolant filter wont help your MPG, but it seems to be very important on the 6.0 to keep the cooling system clean of debris.

Slow down, and accelerate slowly. You will see the biggest gains with these

Here's my opinion on fuel mileage modifications:

1) A responsible right foot - free
2) Monitor package (Insight CS/CTS with EGT and Fuel Pressure) - $560-660
3) SCT X3 tuner with the highest HP file your trucks build can support (bolts ~400RWHP, studs ~440RWHP) ~$420
4) Free Flowing exhaust (3.5" DP, 4" CAT back - Cat optional) ~Varies.
5) FICM tuning (depending on build and head status)

That will yield the best cost-benefit ratio with what I experienced. Reason for monitor above tunes - Fuel Pressure, Low FICM voltage, etc. all rob you of mileage, and may lead to bigger repair bills. If you're after fuel mileage, your out to save money, which means catching issues before they compound themselves.

Or you could be really cool and spend that $1200-1500 on one of these VW golf 1986 diesel
