I have a question. I have 2015 Chevy Silverado rally 2 edition. It has the stock 22' black wheels, it's black with the ghost racing stripes, and bowtie, blacked out grill, 5.3 L v8 and 4×4. "Which is as I understand a 325 cu in." I bought the truck used in 2020 with 70 k miles. I honestly didn't know it was a rally when I bought it. I just thought it was regular Silverado with custom work from gm. Anyways my question is does the rally 2 have any engine or transmission upgrades? Or is it same HP and torque as the regular 5.3? Which is 355hp. I'm never hard on it. I don't hot ride it or let rpms get pass 3500 as long as I can help it. But I've got on it a couple times. Once against another 5.3 Chevy and other against a 2022 new mustang convertible and I pulled them both by a couple car lengths easily. I look at engine and don't see any turbo or superchargers but it's without a doubt faster then other 5.3 . I know I'll probably get hell for asking this lol. I'm no mechanic. I'm a part changer. I can take off and replace any part but as understand no mechanic. Just asking because I'm curious and can't find any info on book or the web thanks

Welcome to the site.

Decals, wheels with red strips, no performance upgrades of any sort. Still a great looking truck though!

Congratulations on your new to you truck!

It could have been tuned for more power by the previous owner.

What's that? Stickers don't make cars faster? Since when? LOL

Donald, these trucks came with several different gearing options as well. Even if yours isn't tuned, if it has lower (higher numerically gear ratios) it will accelerate faster than one with higher gear (numerically lower gear ratios).

Does your glovebox still have a sticker with a bunch of codes on it? If so, tell us what the "G" codes are.

Let's see a pic of it when you can, don't recall that edition.

Very true, it could be gearing. My Z-66 Avalanche has the 373 gear. It’s pretty snappy. My last new Texas Edition had a higher number gear. Part of the package.
