Hello everyone, so I purchase the boost harness from khar tunerz for my Kia stinger 2022 GT1 AWD. I was able to install successfully. I have question for those that have the brake snip or boost harness. How do you know if it’s actually working? Meaning I read somewhere we’re the brake lights won’t work and the car won’t start I’d the fuse is off, but my actually does both the brake lights work and the car starts. For launching do you guys usually keep it under 2500 rpm?
