Hey guys so Im looking into getting a tuner for my 2015 Silverado 1500 5.3 main reason I’m looking into it is just to try and boost the horsepower and get some gas mileage up not looking for any crazy performance just wanted to see what you guys recommend I was looking at the hypertech 3000 I was first interested in the superchips but for the same price I saw hypertech had much better reviews what do you guys use or what works best for the 2015 Silverado 5.3? Thank you

I have the Hypertech Max Energy 2.0. My truck is a 2016 w/ 5.3L and 6L80 trans. I wanted a programmer to improve the drivability, not necessarily improve mileage. The throttle response and shift response adjustments made the biggest difference in the drivability. I no longer have to stomp the pedal to the floor to get it to downshift to pass on the highway. I used it to turn off the AFM and the mileage didn’t change a bit. My truck rarely dropped to 4 cylinders anyway due to a 2-1/2” lift, larger aggressive tires and removal of the lower bumper and air dam. The Hypertech has settings to increase mileage but I would assume that they would make the truck feel even more gutless than the stock tuning does. I may try the economy tuning just to see if it makes a difference.

I tried a hypertech on my 2010 silverado and it gave me audible knock at wot with 87 octane. I wasn't interested in running higher octane at the time, so I just left the stock tuning and turned afm off. Turning afm off was the best feature, but I don't think handhelds do this anymore. At least not hypertech. I believe they're concered about lawsuits from the epa.

 

This doesn't mean it won't work for you. But your really better off spending the extra money on custom tune, and in all seriousness, better sooner than later. Before everyone closes up shop and stops tuning.

I use the FashPaq F5 tuner.
Turned off AFM (though I had already disabled it through AutoSync and BTDiesel) and did the performance tune for 91+ octane.
There is, also, a choice for an 87 octane tune but I wasn't interested in that.
In my experience, it's a very good tuner - I changed RPMs at start and idle. I could, also, tune shift points but I really don't know enough to mess with that.

I'm running a Superchips Flashpaq F5 also.

I'm running the 93 tune

Turned off AFM

Raised idle to 700 rpm

Raised all shift points 5-7 mph

Speedometer recalibrated for 38" tires

This is a very easy to use tuner.

Works as advertised. 

It really wakes up the 5.3 above 3000 rpm.

Totally agree, Jim! I did forget to mention retuning for my 35s (wish I had 38s :D )
Thanks for the info about shift points, I'm going to give that a try. :)

No, because that is a separate function that is tied into the ABS and stabilitrak system.

I have a Diablo I3 tuner and just sold my truck.  If anyone is interested let me now.  It is only a couple months old.

Yeah it was bitter sweet.  But got tired of the round and round with GM and at 90000 it was getting up in miles and 6 years old.  Got a lot of the options I wanted without having to do a whole fully loaded truck

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      Yes.   Yes.   We might be intermingling ideas with the term 'severity', in one of my past vehicles it could pull up DTC via the vehicles own user interface, at any given time when one would do this there would be an assortment of codes that were 'trivial' including 'communication' issues. This would generate a bunch of, potentially false alerts or some many that they would get ignored. Which you mentioned earlier.    You also mention several things that might be redundant with the vehicles own systems or indicators: The truck has an oil pressure gauge, monitoring it via this other system wouldn't be a priority except in comparison to other values or if there is an actual oil pressure problem.   Same thing for miss-fires or other problems, the MIL already signals the operator to an issue...   ...to the point about what one wants to see first, if there is a miss fire detected, I want to see miss fire counts or fuel trims first, if I have an oil pressure problem I want to see the oil pressure first. So, perhaps the 'systems' that are showing abnormalities are what gets displayed first.   I think your device is what connects at the OBD port, ease of use for the consumer, it could still have a 'pass-through' port for a second scanner, computer, etc.   Yes.   Based on my comment above, if an error appears, the report would be more specific to the system having an error.

      I like the idea.  I thought about putting a deposit a few years ago when they first dropped.  I still want to drive one and have inquired about doing this with them, like a ride and drive event they said they are coming but it hasnt happened even with them built in Indiana.

      Transmission Woes :-(

      By asilverblazer · Posted

      That's a tough spot to be in, I personally would question spending 1/2 the book value on a repair vs. selling it as-is.    Presuming you own it out right, sell it for 10k and have a down payment for a replacement truck, or spend 10k on the one you already have...   I still think there is a cheaper transmission out there via recyclers, aftermarket or rebuild. (Cheaper than 5k for the unit)

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

      By Atlas · Posted

      Sadly, there's a drought of good 92-95 4.3 cars at junkyards in the area otherwise I would have gone fishing for parts. Not that they don't come up, there's just nothing good in the yards right now.   I tore into the intake yesterday evening, easier than I thought, and I might have this problem licked for cheap. Two of the intake studs came up with the bolt on removal, no big deal but that's why it looks funny with studs only on one side.   There's pooled gas on both sides of the plenum. Highlights boxed in green. Picture-right side has an obviously split pressure line from rubbing on the #5 injector nylon line. #5's line is worn in that spot but not all the way through. Passenger side intake (picture left), not sure, but I think the pressure regulator is hosed. Rebuilt spiders don't come with the pressure and return hoses so I'll need to replace those no matter what. A pressure regulator is $30 so I'll try that and if I end up having to swap the whole spider, it was $30. I'll be grinning ear to ear if that's all I need.   Parts arrive Tuesday.   Sure enough the shop was here before. That's a new gasket. Vacuum lines and wiring are a tangled mess, I sorted that out last night as well. Spent about an hour just picking up general slack and shoddy reassembly around the engine bay. Cheek-pokered the battery tray, got it all cleaned up. Sometimes things just need a little elbow grease and a few minutes of time to be right again.
