    Rear Brake upgrade, worth it?

    Just saw your message. I bought my Tahoe used a few thousands miles ago amd it already had them. Check out YouTube. There is a truck part company that details the whole install. Truck stops awesome, I’m sure you will love the upgrade if you do it

    I understand. But will calibrating help the ride even a little or no? Do you know?

    Calibrate Magneride?

    I have installed McGuahys (spelling is probably wrong), rear 2” drop springs on my 71k mile 2018 Tahoe premier with Magneride and the ride seems really rough now compared to before. Is there a calibration I need to do on the truck to get some ride quality back or maybe the rear shocks are just...

    Whipple Supercharged Performance

    @WICKEDOWESIX Can you talk about the Lucas Octane Booster? My kit for Gen V 2018 says in instructions not to use any octane booster. Which Lucas are you using? Is it safe for O2 sensors I assume? Can you tell a difference when you do or don't run it? I also have wonderful 91 octane CA gas. So I...

    Whipple Gen V install on my 2018 Tahoe, Finally!

    Oh, I also did a Vacuum pump delete. Removed the pump, inserted the two GM fittings on block. I then bought a like 2012 camaro Brake booster hose for the check valve. I also purchased a random GM brake booster hose for the bends and clamped it all together. Brakes feel great. Oh and the DEI...

    Whipple Gen V install on my 2018 Tahoe, Finally!

    Hello all, I have been dreaming of having a boosted LS (I know I actually have a LT) for years. I finally got the funds together to purchase a Whipple Gen V 3.0L kit and installed it. It runs great and I couldn't be happier. If anyone is planning to get this kit, there were several issues I ran...

    Noise out of passenger side rear door speaker?

    Has anyone experienced noise (kind of like alternator whine but really only at just off idle). The sound is like connected to throttle. There is this low throttle sweet spot when its there and giving it a tiny bit more gas and the sound stops until you get back into that low range again. It...

    Wide band O2 location

    I don’t have the parts yet. All on order. Been saving up for the whipple for a while now. Anyone know about the wiring?

    Wide band O2 location

    But that would be after the primary cats right. Isn’t that bad because cats change the oxygen reading?

    Wide band O2 location

    Hello all, new member but been lurking for a while now. I’m adding a Whipple Gen V kit to my 2018 Tahoe RST when it arrives. I bought an Innovative PSB-1 AFR and boost gauge. I have a few questions: 1) where should I have a bung installed for most accurate AFR? I realize I’ll only be looking...
