I think once you start messing with pulleys, you’ll need to start tuning. The wideband O2 sensor can easily adjust fueling to compensate for the increased airflow into and out of the engine. However, once you begin increasing cylinder pressure, it’s a whole new ball game. I’d be a little nervous...

Do you have documented proof that the 5BW and Escalade-V LT4s are different from earlier LT4s? This is the first I’ve heard of that. The only differences I’m aware of are that these engines are on GM’s Global B platform, which uses a faster and more encrypted ECM, and that they use wideband O2...

I saw that all BW carbon fiber is currently on constraint. Don't know how long that has been going on but it may be difficult to find a 2025 with any CF stages. The absence of blind spot sensors on the manual '25s would be a deal breaker for me. I could live without the volume knob. It would...

I’ve long wondered why GM doesn’t offer FlexFuel capability in its high-performance models like the Camaro, Corvette, or Cadillac V-series. The modern LT-series engines thrive on high octane, and the cooling benefits of ethanol—especially in supercharged or turbocharged setups—are well...

I used the DMS adaptor when I bled my ZL1. It worked okay. I just didn't like the acrobatics you needed to go through to reduce the amount of coolant that gets spilled in the engine bay when you remove the adapter. The Tap Out Tuning kit has a plug for the funnel. There is much less mess and...

More along the lines of preventive. I owned a 6th gen Camaro ZL1 for almost seven years. In year six I decided to bleed the intercooler per recommendation of Ted Jannetty owner of Jannetty Racing. Jannetty likes to bleed the intercoolers while he has the cars on the dyno. Anyway to make a...

Let me start with a rant: Why in the heck did GM not include an intercooler reservoir on its LT4 engines? The Hellcats have one, and so do the GT500s. Why GM insists on a closed system that isn’t truly closed makes me scratch my head. Okay, with that off my chest—I just finished bleeding the...

I just bought an OEM air filter from Amazon for $37.43. Took 3 weeks to get it.

I purchased 100,000-mile B2B warranties with no time limit on my '21 Corvette and '21 GMC Sierra 1500. The deductible is $100. Both were purchased with the vehicle and cost around $3K.

My pleasure. They say imitation is the best form of flattery so I'm glad you want to steal the mod. Inexpensive, easy to do, and make noticeable changes are the best kind of mod.

Hmmm. I have everything at the default settings and the audio sounds pretty good to me. Much better than the Bose 14 speaker system in my C8. Of the three vehicles I drive regularly, a '23 5BW, '21 C8 HTC, and '21 GMC Sierra, who would have thought the Sierra with the basic audio system...

The Blackwing plate is my favorite as well. My wife drives a 2019 Blazer RS.

I've had the hawk02 username for 25+ years. Well before there was ever a Hawk Tuah girl.

My 5BW had all blacked-out emblems. I wanted just a tad more color so I replaced the front and rear emblems with black with colored center.

I just received the front and rear emblems for my 5BW from 404parts.com. Good price and received those emblems in about a week.
