Hey I have a 2000 Chev. Silverado 2500 with the 6.0. The previous owner installed some NuImage white face gauges and got all of the gauges good except the fuel gauge and the speedo seems to be reading 7mph too low (causing the odometer to be off, making it seem like im gettin less then 10mpg!) Is there anyway to reset the gauges so they read correctly? If not, is there anything I can do besides changing out the whole cluster?

 

Thanks!

Hmmm, 2500, 6.0.... maybe you ARE getting less than 10 mpg. :cheers:

 

Really though, what do the gauge faces have to do with the odometer being off? I'm guessing you're thinking he pulled the needles off and didn't get them on in exactly the same position? That wouldn't affect the odometer. It has no idea where the needles are pointing and really doesn't care. It gets its info based on the speed signal.

 

Does it have stock wheels/tires... or at least the same size? That would affect the odometer if the PCM was not recalibrated for the tire size.

Yes, the needles were taken off and not placed on correctly IE: when full the gas gauge reads a hair below the 3/4 mark. I thought the odo might be off relating to the speedo because you have to get rolling a good amount of speed before it even comes off the speedo stop. and at even 10mph on the speedo gps read 17mph and stayed about 7mph off. The tire size is 265/75R16 but when a 245/75R16 (stock size) was put next to it off the truck they were really close in size. It had 285/75R16 all terrains on it when I bought it and even with a superchips programer set for 285's it wouldnt read correctly. Right now I am seeing 185-195 miles per say 22 gallons of gas when I fill. I know my mileage drops with the ND winters, but it hasn't got below 20 degrees for a long time. In the summer with the 285's i was seeing 230-240 miles on the odo with the speedo reading wrong because of the bigger tires. Whats my next step here? New cluster? Bring it to the dealer and see what they can do? (Boss wouldnt be happy, I work at a chrysler dealership and my dad has been a manager there for 25+ years haha) Thanks for everything so far your great.

A dealer isn't going to mess with trying to get the needles in the right position. All they'll do is pull the cluster and send it to an authorized delco repair facility.

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
