I'm in the process of building my 2015 Silverado 5.3 and I'm trying to figure out what parts I should get as far as preformence I'm limited on money but I want to start on it

How far are you thinking of going with the mods? Upgraded exhaust? True Dual exhaust? Cold Air intake? Blower? Turbo? Your end result is a big determining factor on where you start. right now the most complete balls to the wall kit i have seen is the Armageddon Turbo kit. Comes with everything you need is included. Including install! $9k. On the other hand, my max mod will be Airaid MIT, Borla exhaust and a BB tune. So, like i said where do you want it to end up?

The sky is the limit! But as Willshire said, what your end goal is determines what would be the best path for you to take in regards to mods. Being limited on budget, as you said I would suggest starting with a cold air intake and tuning. We have our Winstorm line of intakes that there is a 5.3L one available, along with a mail-order tune to go with that. As you add mods down the road we can update your tune. Then add longtube headers later, or if you have it in your budget now. A catback will not gain you on the power side only improve the sound, but the headers will also improve the sound also while gaining power.

 

For "balls to the wall" I think this truck covers that!

Thanks for the input guys I'm saving up for headers at the moment and surprisingly I was pulled on by a guy in my club and all he had at the moment was a catback exhausts , even tho I had launched on him. We both have dropped 2015 silverados only difference was that mine was the exhaust

You guys do mail order tunes on the new LT series? What mechanism do you use to accomplish this? AutoCal?

What long tube headers do you recommend?

ARH

I love the sound of borla exhaust but would rather have performance of arh headers with 5.3 denali but dont have the funds for exhaust and headers. Could i do electronic cutout or something else to get the sound?

We sure do! We have our own device called the Mycalibrator and our own software which allows us to create a much more in depth tune.

Good job fellas. In the video, I noticed the truck surging off the line in first gear. My truck sometimes does that but only if I try to do a boosted launch. I believe that is the trq mgmnt kivking in. Have you guys revised the tune to eliminate the rocky launch.

Thanks! That is actually more of the stability control as you cannot turn it off completely, the truck was gaining and losing traction. Kind of like a 4WD wheel hop. Our calibrator worked a long time on dialing in the adjustment for the torque management to keep the drivetrain happy while still being able to put it down when you hammer on it!

 

BTW... Stay tuned for more from this truck this summer :flag:

I don't think the 9k price includes install, just for the kit

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      By CNH-320 · Posted

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
