I currently have a 2002 Silverado 1500. I am wondering, though, what type of MPG a, say 2002 2500 diesel would get with a proper tune. I have heard something on the order of 30 MPG.
Is this info accurate?

2002 ECSB, Nelson Tune, LS1 electric fans, 145A alternator, K&N FIPK, 160º T-stat, TB coolant bypass, Corvette servo, 4 headlight mod, blue LED gauge cluster
NO, the first gen LB7 Duramax 2001-2004 will get the better milage of all the rest, but it is a good 21-22 is what to expect. My best is a 20.95 on a tank, with a STOCK tune, if you put anything else in there, the power is soooo addictive, the milage will suffer!
Unless you can control the right foot that is.
So folks have tried to convince me they were getting 27, but I still call BS to this day, and some say 24, alittle more believable, but not totally to me.....just me that is. I believe they were going off of the DIC and not hand calculating, and when a tune is thrown in, the DIC will be off nearly all the time.

2006 1500 CC/SB with the 5.3L and Nelson PCM.
soon to come is a intake and exhaust. (wifes truck)
Other vehicle is a 03 2500HD CC/SB 6.6L DMAX straight piped and Edge stacked with Superchips and gauges, Loves to eat rice for sure! Fartcan exhaust makes it better!
Well, looks like the Silverado's days are numbered. I can't afford the gas for this thing. Costing ~$500 a month at today's prices.

Milage that is posted on window stickers is done via a car treadmill with no wind resistance.
99RCSB Broke because I wasted thousands and thousands of dollars on my truck.
There are mileage tunes out that have seen 27mpg for the LB7, but with the higher price for diesel, and higher maintenance cost its hard to justify. Cost me $114 to fill up last night....

The best advice I have ever heard:... Only take B( . Y . )ST advice from someone that is CURRENTLY running a turbo setup close to, or bigger than what you want......
Which tune is that?
Have you got that tune?

Step 1. crus at it.
Step 2. get a hammer.
Step 3. torch it.
A good handheld tuner has a few different types of tunes. A Economy, Tow, and Performance. The Economy tune usually yields something close to 25-27 mpg, depending on how deep you foot is stuck in it.
2000 ECSB 6.0L
TORQUER V2 CAM ● COMP 918's ● 7.4 HARDENED PUSHRODS ● K&N SERIES 77 CAI ● 80mm BBK ●PACESETTER LT HEADERS AND 3'' ORY ● SUPER 40 FLOW ● 3000 STALL ● 4.10s ● BUILT 80e ● VORTEC PERFORMANCE TUNE ● MSD 8.5mm PLUG WIRES● ELEC. CUTOUT ● UD & ALT PULLEYS ● FLEX-A-LITE E-FANS ● 22" CENTERLINE STINGRAY III's ● LUND FIBERGLASS TONNEAU ● 2" LEVELING SHACKLES ● 12K HID LOWS & FOGS ● LEDs ● DEBADGED ● WHITE-FACED ESCALADE GAUGES ● KICKER 450.1 ● 2-CVR 10's ● DS60's ● K693's
I have tried 3, and best I could do was 21.
I am a regular visitor on the Diesel Place and I can assure you that some claim 24 which is still hard to believe, but more plausable than 27.
EFI Live is the best tune going IMO for the duramax, and of course the LB7 is the better of the milage engines, but to say getting 27 is common........Still hard for me to believe.
