I have a 16 viper with the MPI kit, it has the EABC kit and it doesn't work worth s**t. If I am in lower elevations for any period of time I adjust the wastegate, otherwise I just ride it easy until I get some elevation.I just picked up a 2015 Viper M-TX, has the 190 MPI kit, (dealer installed when new). It's been run elevations from 6k to 10k, and most of my riding is from 3200' up to 6000', with an occasional trip up to 10K. With this swing in elevations, should i install the EABC kit, or will it be fine as is? Is there a soutce for the EABC kit since MPI shut their doors? Currently don't have an AFR gauge, so i don't want to mess with any of the GEMS settings until I kniw what I'm doing. FWIW, this is my first turbo sled.
