which mods are best?
Picking up a 1999 7.3 6 speed 4:10 75k miles next week.
what order should I add these three mods, can't really afford all at once.
Tuner/chip, air intake, larger exhaust.
I pull a 20' cargo trailer 10k lbs 50% of the time on highway.
Other 50% city driving
Looking for better gas milage & overall health for engine. I will not be hot rodding.

X2.....An EGT gauge is a must with a tuner. You have to monitor the exhaust gas temps so you don't FUBAR the pistons.

Tuner vs Chip. Are they the same? I have a DP on my 6.0 which has been great. The F5/F6 chip from DP is it differant?

The WW is on early 99's also.
Oh and great find, a 99 with only 75K, wow. I'm at 144k with a 03....lol

Seems like everyone pretty much covered it. The 6637 intake is cheap and does a great job.
All these mods can be bought from Clay at Riffraff. He can get you everything you will need for a great price (no need to shop around) plus you can't beat his customer service.

This one I'm getting has the small mirrors, maybe it's an early 99.

Lift the hood and count the bolts on the compressor housing on the turbo. Four bolts = early 99, five bolts = late 99+. Also, with a manual, you can control surge easier by down-shifting a gear. WW may still be needed though if it's a late 99, but not necessarily if you're okay with the down-shifting method.
