Anyone out there with VRF TUNING Experience? Just bought a VRF TUNNG KIT from Vivid Racing and wondering if your experience is:

It‘s GREAT! or It SUCKS! Do not want to F up my ride.

Any experiences welcome.

Almost have my rebuild done. Looking Good, so far. Don’t want to OBD II my ride into limbo hell🤪🤢💀
