Dyno'd 5.3 Lm7 Silverado

Mods on ruck; Gibson Dual rear exit Exhaust

Ebay Intake

Predator Programmer

 

So lately Gio has been wanting to tune some domestic cars and programs just to gain knowledge and insight. He has a somewhat eccentric boss who is really into having modded vehicles and so my brother convinced him to get himself any type of programmer and he would tune it. Owner bought himself a Predator Programmer. The truck is a 5.3 LM7 with 208k on the clock.

 

The Predator tunes were absolutely worthless, 16+ air/fuel ratio loss over 20whp and 20ft ls tq, owner of the truck was changing skin color because he was so mad. Luckily Gio was able to make his own tune and good some decent results I think. More mods coming in the near future I'll keep you guys updated.

 

Orange = OEM tune

Blue = Predator Tune :thumbs:

Green = Custom Tune by Gio

That made more power than I thought it would. 2WD I assume?

 

 

 

Yup it is a 2wd. I'm not really sure if these numbers are normal and what these trucks put down stock. Most imporatant things are the gains from the baseline and the sotp imo. Owner was very happy as you can tell from the vid, first timehe romped o it after tuning the truck fishtailed and was aiming towards the light pole!

Yea i was also inmpressed with the numbers.With LTs and a blackbear tune you might be close to 300 mark.

Stock hp rating from factory is 295hp and 335tq, when I dynoed my truck stock is was getting 220 RWHP and 253 RWTQ, when I got my tune and intake it jumped up to 250 RWHP and 300 RWTQ, factory exhaust still on but mods to come are new cam, headers, custom dumped exhaust and 3.73's instead of my little 3.23's might even go 4.10's but unsure. new tq converter and corvette servo and hopefully I will be done lol.

Was any logging done here?

 

Was it knocking on the diablo tune?

 

Looks like a case of a 93 octane tune being loaded to a truck with a tank full of 87 octane...

 

If it was on the dyno, theres no need to wonder why it lost power, all the answers are right there in a datalog.

Going to send you a pm, Predator Unit is nice and easy to use. I just wanto figure what happened here.

 

One note, for some reason off the shelf tunes never seem to work down here in South Florida. Wheteher it is a JWT(Nissans), Phearable(Honda), and maps from DSM's. The same symptons of running lean appear across all makes. Maybe it has to do something with us being a bit under sea level and very very humid?

 

BTW I also really doubt some guy who is nowhere near a vehicle can e-mail a tune that would be optimal or at least as good as someone who is there live tuning.

I can see your point in the matter but, here's what BlackBear Performance does or at least to my knowledge, They initially ask you certain key points to what you have recently done to your truck, you tell them and they send you the autocal tuning log device, from there you hook it up to the truck run some data logs of driving then once enough is recorded, you send them off and he starts fine tuning an PCM then sends it to you, once you install new PCM you run some more data logs and send the data once more, the replies are very quick, within a few hours, and from there he can tell you what to fine tune if needed to run optimal. Now would this kind of tune be good to use if you installed a new cam in the truck, no since you would directly need the tune after install, but myself and others on here can say that these mail order tunes are WAY better than an Diablo handheld or any other handhelds of the matter.

Sounds much better than just a mail order tune for sure. But I still prefer tuning it myself with the Predator Programmer.

I might agree, except that we are in South Florida, and all our tunes are developed here :thumbs:

 

Where are you guys located?

    • Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.    
    • apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.
    • yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
    • 286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔           
    • hello I recently bought a 2012 gmc 1500 with a 5.3 and have a AFM disabler on it I'm interested in doing a cam but I'm worried if I remove the AFM system I will fail smog does anyone have info if they are able to detect that or a work around to it (not talking about hot smogging) please let me know thank you
