Pto/idle Up On 5.3l 04 Silverado

I work out in the field, and have a 2500w power inverter in my truck to charge cordless drill batteries, laptop, and my airdata multimeter. I also charge my camper battery through the trailer harness, and have to jump start the occasional vehicle.

 

I know some vehicles have the PTO function, and you can bring the idle speed up from the cruise control switches when you turn the PTO on. I was wondering if the idle up/PTO function is available on a 2004 Silverado 1500 w/ the 5.3L. Some have told me no, some have told me yes...

 

I know some commercial trucks have the idle up function, where if the vehicle is parked (parking brake on), you can turn the cruise control on, and when you hit the set button, it will run the RPM up to a certain point. Hitting accel will raise to up to a max setpoint (usually a few hundred RPM above the base point.)

 

Is this an option that can be turned on inside the PCM, or through loading a different program to the PCM?

      Some Assembly is Required

      How many years have I pointed out every point in that link to the folks here and been avalanched with criticisms and outright hostilities at times? I ran counter to even the great CUSTOMBOSS and Lake Speed Jr and the half dozen experts on YouTube and in the final.....GM, Physics (Stribeck) backs that Grumpy old Bear.    Honestly, I never said a thing engineering hadn't studied silly and laid in concrete during WWII. But I'm old, the information is old and yet, the Laws of Physics are eternal.    Okay there is one exception. I vehemently disagree with their use of the word 'tolerances' when what it meant is "clearance".   The clearance is the distance between two objects. The tolerance is the degree of acceptable variation permitted in that clearance. I.E., piston to bore clearance is 0.004" with a tolerance of +/- .0002" so the clearance is in specification if it lies between 0.0038" and 0.0042". Cutting that 'tolerance in half has ZERO impact on lubrication requirements. Makes for more difficulty in manufacturing.  But a tighter clearance 'MAY'. Depends on finish. Anyway....   It's one of those statements made by people to make themselves look smarter than they are to convince people who are as un-enlighten as they seem to manipulate their behaviors. But hey, the blind leading the blind puts them both in the pit.

      Gas Prices

      By Grumpy Bear · Posted

      Out and about yesterday on a long Saturday drive I passed a lot of Shell stations. My preferred, so I pay attention. Lot's of small town Illinois so not six stations in three blocks like the city.    Everyone of them over a radius of say 100 miles had regular at $4.19 but one which was the one closest to home at $4.15. However Premium pricing varied greatly between 85 cents over regular to $1.50 over. I'm not counting the price of the station with the lowest regular so the reference is the same for the remainder and all within the same brand. However the spread discrepancy holds across all brands.     @txab, any thoughts on that?

      Future GMC Jimmy

      What are your thoughts? The Chevy Blazer relaunch was an epic case of 'lunchbag letdown'. Jeep Wranglers and Ford Broncos stick out like a sore thumb.    The AI photos do not look like a 'retro version', but shrunken Tahoes. Get away from the 'futuristic look'. I've seen two concepts. One had rectangular headlight like a Rivian and the other way to big should include dual round headlights like the early version.   If not this would look OK   At least it has GM styling (albeit the K2XX) A lot of the images floating around look like Bronco IIs or the current Bronco. Looking at the Broncos in my area (central Ontario, it seems to be a mix of 2 doors and 4 doors, 'mall rated' to ones that could go offroad.    I'm sure a AT4 and AT4X RPOs could be outfitted similar to a Rubicon if the braintrust understood the whole offroad scene. Crosing my fingers that if it does see the light that the front air dam/bumper doesn't extend below the center line of the tire...

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      And overpriced. I was in the Oshawa Truck Plant when they were being built. Very few. I could count on one hand how many I've seen since
