Just ordered a Diablio Intune i-1000 tuner! $50 off and free overnight shipping from autoanything.com. Pretty sweet deal. Hopeully it will arrive by Saturday

I will be very curious to see how this works out for you. Is there any reason why you didn't go the Diablew tune route?

Well I got it for now since the winter is rolling in and the MPGs going down because of it, I figured it wouldn't be a bad idea to try the MPG booster on the Diablo. Plus I'm now planning to upgrade to bigger tires right after Christmas so this way I can adjust the tire size calibration so everything stays correct and maybe I'll find a few other things to play with on there. I plan to go with a custom tune later on but after I get headers and anything else I want to do to the engine so it can be tuned properly

I'm interested to see the results of this tuner. I'm in MI and the cold is settling in... MPGs have tanked. I'm down to about 14MPG AVG(city) with the 275/60R20 Duratracs.

I averaged 15 MPG highway for the first 45 minutes of my trip home today (2 hour ride total) no traffic at all, just straight cruising at 70 mph. After the engine completely warmed and the transmission got to 150 degrees, it finally went up a bit more but only topped at 17

 

I normally get 20-22 the whole way.

Got the tuner in today. I ordered the AMP plug and play pass through harness so I can run my amps and the tuner at the same time. I'll just have to unplug the amps and use the tuner for the weekend. May just try installing the tune and then unplugging it and rep lugging the amps. Anyone know if the tune will work fine without being plugged in after its downloaded?

Finally made my GMC cover plate last night. Glad to have that bow tie covered and a GMC logo back there.

Thanks for the update Mike. Good luck with the tuner. Looking forward to your testing. Up here in the North East. it has gotten very cold like the rest of the country. My MPG's are down to 16.4 around town, from an average of 17.8.

Looks good. Just found out there is room under the seat barely for my JLw3 12" that has been collecting dust. might try and throw together a box soon. Might be overkill with a 1600W amp, but I did have it in my Z06.

If it's worth doing, it's always worth overdoing [emoji41] put the big subs! Just try to get a ported box so they really hit hard! I compared my dual 10s (mine is a ported box) to a friend with dual 10a (his are in a sealed box) and the difference with how loud they are is incredible! Of course, mine had double the power of his though [emoji23]

 

Ps. My girlfriend and I were on our way to dinner tonight and we had a song on with plenty of bass, the amp drew so much power it made my headlights blink on and off with the beat lol

Nice. No lightning cap? I have thoughts of building a ported sub box / under seat storage system...

Lightning cap?

Giant capacitor, 1 farad usually, in line to help with big amp draws on the system. will help/minimize lights from dimming. Car audio capacitor, strike cap (other names). They help a lot and are relatively cheap.

Not a bad idea, especially with all the computers in this truck. There is A LOT more power being drained or a lot less being produced by the battery in this truck than my Yukon because I used to use both 55W HID headlights and 55W HID fog lights in that SUV and it rarely had the lights dim on a good bass note, and when it did dim it was nothing like what this truck does. This one takes a big hit on the headlights TBH. Now that you are showing me this it may be the next thing I install. With how many computers are in these trucks, the last thing I want is for one to possibly get fried by a power surge somehow created by the amp

    • Late reply, but yes—it works on the SLT trim. Compatibility comes down to the plastic shroud shape behind your mirror, not the trim badge itself. On the SLT with auto-dimming, it uses a plug-and-play Y-harness off the mirror/rain sensor power, so no need to run wires down to the OBD port. If anyone's ever unsure about fitment, just drop a photo of your mirror housing and we can double-check it.   Appreciate the detailed feedback on the install! On the windshield glare—we actually took feedback like yours and developed a dedicated CPL (polarizer) filter to cut down dash reflections on sunny days. If you're still running the cam, shoot me a DM. I'd be happy to send a CPL filter over for you to test out—no charge. 
    • There are no stickers in your glovebox?
    • Look at the numbers on the stickers in the door jam...
    • Yes, every time the developer updates his code, you must recompile. I will private message you with the latest because it changes pretty much with every version.
    • After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.
