You can... but you'll notice alot less power and you may get some ping under load which isn't a good thing. My 2003 had a tune for 93 octane and could get away with 87 without issue under normal driving but when I was hooked to a trailer, I had to make sure I had 93 octane or I'd get ping (early detonation)

 

Try a tank and see how it goes. In most cases, the "handheld" tuners are more conservative in the programming than true custom tunes because they wont their tunes to work with "all" trucks in various conditions so you should be fine. :thumbs:

Yeah I heard fromthe other people about the ping. Have u tried the transmission settings alot with the tow setting? Any feed back on those, I have only ran econ

You can turn up the line pressure for a faster shift without issue. Quite frankly, a faster shift is what you want. It produces less heat which helps the transmission to last longer.

      Trading 7.3 (Godzilla) for G.M.C gas

      By KARNUT · Posted

      My nephews 7.3 got noisy right around 100K miles. While replacing the engine he drove his old 6.0 Chevy that had over 200K miles on it. It an old reliable backup. I haven’t been around the old shop lately. I’m curious to find out if there using the new GM heavy duty gas.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I don't know if you or anyone enjoys it or not but, why not share it. It's GM "truck" related and we're in the right place to discuss that 😉 I'm also working on some creative writing skills, I'm not quitting my day job to pursue that, either!   As I said, I've hit a wall because I'm not making any progress, and the progress is the fun part for me.   The idler pulley and EGR valve came in. Against better judgement, I went out there last night and put both of them in. I was able to get a nut on the back of the bolt on the side with the broken flange. There's enough flange still there that I can get that side of the EGR to snug down. It's not perfect, it's not "right", but this is the fix I have for now. If I decide to keep the rig, I talked to a guy locally who will sell me a complete intake for $100. If it's my truck, a broken flange like that would bug me too much. Yes, I'm crazy. But I embrace it.   Pulley on, EGR installed, started the truck. Great...still have a pulley squeaking like mad. That was the first disappointment. I thought I had pinpointed the problem. Before I replaced it, I sprayed the back of that pulley with PTFE and it would shut up for about 30 seconds. Is the squeak actually the belt? I'm frustrated.   SO then I decided why not disappoint myself twice, so I took it for a spin and sure enough, the CEL set for P0401 insufficient EGR flow again.   I had some extra time, so when I arrived home, I decided to ask AI about my EGR code. We had an interesting conversation.   I asked how to tell if my MAP sensor is bad and if that could be setting an EGR code since a bad MAP may not be sensing the requisite drop in manifold pressure when the EGR activates. I gave it the MAP value at idle and it told me to blip the throttle hard and watch the MAP reading. It said no, the values appear normal and it's reactive to pressure changes, and then instructed me to test voltage at the harness. I don't think it's the MAP sensor. Interesting, though, I gave it MAP reading values in inHg, and it thought I was using PSI, so I had to correct it. AI is a very dangerous tool if you aren't treating it like the machine that it is.   Then it walked me through testing the EGR and harness. It took me down an interesting path. It was referencing a gray wire and a white wire so I told it I can't tell the difference on my harness because it's dirty and old and both could be white or gray, I'm not sure. So it gave me a more accurate description of the ABCDE pins on the connector and started referencing pins instead of colors. Helpful.   The EGR harness has 12v power, and it also has 5v reference power from the PCM. What I'm unclear on is there's a ground wire and I thought AI had said that one of my tests revealed the ground in the harness was likely bad and it instructed me to wire a test ground. I got distracted and navigated away from the AI conversation, and when I went back and asked for clarification it said I must have misunderstood. (how rude- next time I'm saving the conversation!)   But I think it was onto something. I recall NOT getting 12v when I tested the power wire to the ground wire, but I did when I tested the power wire, grounding the voltmeter to the engine block. AI said no, the ground wire is actually for the PCM, that's how it commands the EGR on by grounding it and so the circuit should be open with the key on (i.e. EGR off). But I think there's also a static/overall ground that should always be grounded, and if that's bad, then the EGR isn't activating when the PCM commands it on, and thus setting the code.   There's a bunch of other tests it suggested, back-probing with the EGR plugged in and engine running. I need to get some time to focus, and not just tinkering after a long day.

      the 7.3 lifter issue is real, not few and far between.  my 6.6 gas does not use oil.  the 7.3 with 4.30 gears pulled hills better and felt better off the line. the 6.6 gets the job done though. mpg sucks

      are you talking about the loud whooshing, grinding type noise? mine does it too

      Slate Electric Truck

      By Donstar · Posted

      I am a huge fan of the Slate.  (SUV for her, base pickup for me.)  Unfortunately, there are no plans to sell in Canada but maybe this will change.  I think if/when Ford offered a high range. EV Maverick, it would be my first choice.
