I bought a SCT programmer it was $420 for the tuner and the set up, I had a bunch of oil leaks in the valley so I bought a complete o ring kit, it had the turbo pedestal seals then I bought a turbo rebuild kit for about $90 it had seals and bearings etc. (My turbo had leaks and was missing some bolts) I bought a wicked wheel and it was $70, I did a ebpv delete which I gutted the pedestal and plugged it and reinstalled it with new o rings. I also removed the flap from the exhaust side of the turbo and plugged it also this cost about $40 for plugs and taps etc., I installed a diamond eye exhaust system w/ straight thru muffler $275 or so with tip (got on sale) I bought gauges for the pillar, boost , transmission temp. And exhaust temp. These are very necessary to monitor everything. This was about $260 I also did a 6637 cold air intake with a 4" long piece of leftover exhaust, a 6637 air filter from Napa and a 5" clamp. $45
I checked my mileage again this morning and running the 90 hp tune and driving mixed city and hwy and driving like a bat out of hell I got 16.93 mpg and that is driving 75 -80 at times 2000 rpm mostly

Oh and by the way my mileage figures on the first post was on the 45hp tune, it seems to get better on the 90hp if I would slow down and drive conservative.

Depending on stop and go - I've easily got up to 16mpg in the city, and over 20mpg on the highway.
Stock tune - just a CAI and 4inch exhaust.

I averaged 16-17 from Oklahoma to Virginia about a week ago with a dp tuner, 8' lift 38's 6637 intake, straight pipe, ect...

17mpg is my all-time average for highway. There was this one time & one time only I got 19.4mpg on a trip from Smithfield, RI to Newark, NJ(303.2mi round trip) & since then I've NEVER have been able to get even close to that ever again. I started the trip off with a full tank & when I got back, I had a hair below 1/4 & was able to finish the tank off with 344.1mi. total.

I'd start by looking at this Video - Trey does a good job covering it.
the EPBS tube and Sensor are a good and easy starting point

Thanks everyone for the input. I do have gauges etc already. I did have the 6637 napa filter too for awhile. I think I will be going back to it. Also doing a ebpv delete. Thinking a wicked wheel would be nice. But I will need to see what others say about it. The little bit I've read there are mixed reviews.

The WW in a stock housing just help's to cure the surge issue - nothing really for economy about it...
I heard you will loose a couple pounds of boost - but nothing major.
It's a quick fix if your doing a bit of towing and not planning on upgrading the turbo anytime soon.
But if you're planning on a turbo upgrade - save the $$

I have an 01 xcab short bed 4x4. I get between 14-16 city and 17-21 hwy depending on time of yr. Last trip from AL to SC 450 miles in Sept I got 19.5 going up and 20.3 coming back all hand calculated filling tank to the top (who knew over 12 gallons will go in the top quarter of the tank including the neck). That was driving very very conservatively and coming back I went through the hills in NW GA and NE AL.
Next trip from Huntsville AL to Nashville to Chattanooga and back with driving in both cities in TN, I got right around 18 because of the hills and the little bit of city driving.
I have AFE stage II, CFM+ manifold, intake air heater delete, mbrp 5in tb exhaust and canned tunes but I have got my best on stock tune or eco tune with low boost response turned down to use less fuel. Going to be getting ebpv delete pedestal combined with 38r and high flow outlet and bellowed up pipes so once I do a long trip with those I wll post numbers. I also run the tires in my profile pic which are 267/75R16 Nitto Terra Grapplers with 80psi in front and rear (bumpy but they roll good).
I think it really depends on how patient you are because I have gotten as low as 16hwy and as high as 22. The best fuel economy mod is a very light foot. O yea I run DIESEL KLEEN every tank too it seems to add about 1 maybe 2 mpg depending ont the conditions. My truck seems to run best in the fall and spring months
