Hello all, been lurking a while but now need some help. I’ve got a 2017 Silverado crew cab, with the 5.3 6spd, 4x4. It’s not a max tow, but it does have the factory hitch and trailer brake. It pulls my travel trailer well, it’s 28ft but a bit light, ~5400.

It looks like black bear and diablew are the recommended custom tunes. I’m not quite ready to drop that kind of cash. So looking for a good off the shelf programmer that may wake up my truck a bit. I’ve used a flashpaq on previous vehicles and wasn’t impressed. Right now I’m looking at either a bully dog or diablo. Just curious what you all use or recommend? Thanks.

black bear has better reviews, but use 91 octane and 175 t-stat

I went with Diablew. Very happy. Lew is very response to all my questions and got my tune back within a few hours after I sent him my logs. Either way you can’t go wrong.

You can get either a Diablew or Blackbear tune for around $600 or less. I would honestly just save your money until you’re ready to go that route. You’ll be glad you did. Those handheld tuners can only do so much.

 

I’ve had a Blackbear tune on my 2015 for a couple months now. My mods are longtubes and Air raid CAI. The drivability of the truck is so much better then stock. The truck gets off the line so much smoother, shifts are firm and predictable. I don’t really hot rod the truck but you can feel the added power when you get on it.

Does anyone use HPTuners for the these newer model Chevy's?

Yes but I believe the computer has to be sent to HP tuners to be unlocked so it ends up being north of $2500 to get the 2019s and newer tuned. GM is making it harder and harder for the computers to be unlocked.

I have the Trifecta Elite tune on my 2018.  I installed it at 1,000 miles and have had zero issues.  The good thing with their Elite tune is that Trifecta will make changes to the tune if I ask, which I have.  That way if/when I install any performance parts, they will make a change to my tune to take full advantage of the new parts.

 

They used to claim that if you remove the tune, GM would not be able to detect that you had a tune installed. Not sure if this is true but I have not had any problems at the dealership.

Drop the cash on a custom tune otherwise you will waste money on an off the shelf.

if you want a cheaper route than a tune, go with the bored throttle body and throttle enhancer from solar performance.  and pick up a stability trac ABS disabler harnes.  these trucks are way detuned by the saftey system.  you'd be surpised what the OEM tune can do.. also delete the airbox restrictor panel., run in tow haul and 5th gear. no tune needed , and no need for a v4 imobilized  thing.. running in any gear exept "D" turns off v4

 

if you need more power this is a in the Power enrichment tables, but i would start with cheap mods first.  use 91 octane too and trans t-stat delete

Just throwing out another option that not many know about. I have HP Tuners and I tool around a bit with things on my own. But, there's SO much darn knowledge that's needed to tune these Gen V engines/transmissions. It's not like the old Gen III's with 4L60's. Direct injection and cam timing is quite a beast to understand. 

 

With that said, for about $700 you can acquire HP Tuner software and pay some of the best Gen V tuners out there to tune your truck. These are guys that thoroughly understand how it all works and don't just band-aid the driver demand tables to make it "feel" better.

...and maybe that describes Justin and Jenna at Blackbear and I just like to make things complicated :) 

But spend some time on the HP Tuners forum, specifically the Gen V GM section and you'll start to notice the centers of influence on there. There's a LOT of people out there who call themselves a tuner. But I tend to trust the ones who publicly share their knowledge, it gives me more confidence.

Lucas, great points! Trifecta claims they flash a tune without any PCM unlock. Do you know if they just Are they just adjusting pedal/throttle inputs? Or are they adjusting fuel and timing tables? The way it’s marketed it sounds more than just the former, and that would not be worth $500 to me.

Quote from Trifecta:
“- Its octane adaptive: Meaning this is not a '93 octane only tune'. This is a full fledged calibration for both he engine and transmission. You can use 87-93 octane as you see fit and the computer will self adjust power output. You will see best gains and MPG on 93 however.

- You can flash back to stock at any time using our software. The factory calibration is included with the file we provide you so you can quickly and easily switch from Custom to Factory for any dealer visits

- You have Driver Selectable Vehicle Modes: These are custom driving profiles we programmed into the calibration. You switch between them using the Cruise Control button. We include an ECO mode and a Performance mode you can switch back and forth to, on the fly. When CC is On you are in ECO mode. When CC is Off you are in the Performance mode

    • Progress... sort of.   Intake is disassembled, spider is out, fuel lines removed. Used a torch on the stripped screw with the lower intake off, much easier when I've got the intake sitting on my workbench, I made it talk. Walked right out with a pair of vice grips once it was nice and toasty hot.   New parts are piling up on my service cart waiting to be installed. Distributor, temperature sensor, new gaskets, fuel line kit, themostat, water neck.   My new pickle is I don't want to spend $600 on a replacement spider. I'm not sure IT is bad. I'm probably splitting hairs. Or it's $300 to send mine away and another 3 weeks of the truck just sitting. I have half a mind to assemble everything with the old spider to see if I can get away with just replacing the fuel pressure regulator to be safe. The obvious issue was the gushing high pressure fuel line which will be replaced. Getting to the spider really isn't that hard, and now I know what I'm doing , swapping it would be a breeze should it absolutely need one. Stupid, or smart?   The part that gives me pause is replacing the distributor. Well, it's already out. And I didn't mark it, whoopsie! Engine was at TDC when I removed it, I know that, so upon correct reinstall the metal tip on the rotor should point to the TDC mark on the distributor because that's where it was pointing on the old distributor. Worst case I'm a tooth off and have to re-stab it.   But then, what? I assume the truck will start. It doesn't appear the timing can be set. Here's the problem: These distributors can't be rotated but a degree or two, by design. What I read is Cam ****** needs to be -2 to +2 degrees, ideally at 0 (and checked/set above 1000 rpm). There should be enough wiggle to get that properly set, but checking the reported value is another potential issue. My Actron 9185 scanner says it supports enhanced GM PIDs and Cam ****** is one of them but it's unclear that I'll be able to correctly see it over OBD 1.5. I can see why people end up junking these things with life left in them. They're an absolute nightmare with tweener-year diagnostics/electronics and unobtanium parts.   Fingers crossed it starts and idles nicely. There can be hope, right? I'ma buy a lottery ticket the same day just in case.   Next steps..DO IT. I have not installed an intake before so I've been reading and watching a lot. Some say NO RTV except on china walls, some say DO RTV on water ports but not fuel/air intake. 1/4 or 3/8 bead on China walls? I think my strategy will be, obviously, RTV china walls with overlap on the gasket corners. Chapstick-style RTV the water ports. Leave intake ports dry. The only set of intake gaskets I could find locally are Edelbrock performance gaskets (uh...for an asthmatic 190hp V6? LOL) so we'll see how they do.   #NoToolLeftBehind. It took an hour, but my recovery mission for my deep 10mm socket was successful. It had rolled down the bellhousing and wedged itself between what I think are the fuel lines? I couldn't see it at all, but with a junk antenna I had laying around, I blindly went poking/sweeping for it, heard it clink, raised the truck, and caught a sliver glimpse of chrome with a flashlight way up there in Narnia. I had pushed it farther along the lines holding it captive, but within access of severely improvised tools, poking and cursing at it to finally knock it free to where I could get a fingertip on it to bring it home.    Not much to see.

    • It wouldn’t have happened if the government hadn’t mandated outrageous fuel mileage standards. It does very little for the consumer. It adds cost. Back during Covid there was a chip shortage. They gave a rebate for your truck if it didn’t have the chip to turn on cylinder deactivation. It was 50$ because at best you may see 1/2 a mile increase per gallon. Splitting hairs each fuel mileage trick wasn’t mandated. The government doesn’t do the engineering work and say use this until it’s already in use and they like it. The fuel mileage was mandated. And those add ons the results. There’s a mandate and they are the results.
    • It was never mandated.  Ever.    Automakers were incentivized to install it by getting CAFE credits to help with their vehicle fleet fuel economy scores.  They were being handed money/CAFE credits to install it.  Which is NOT a mandate.       The current admin removed the incentives that were behind them installing it.
