Hello, New to the group. just bought my first GM product. 2017 Chevy 3500 LTZ. i am looking at all of the options and it seems that it is very limited. which is fine. i have found that the Banks Derringer seems to have the best reviews, the question i have is... has anyone ran an OBDII splitter with an alarm and a tuner running together? the truck i bought has a KARR alarm system on it and it plugs directly into the OBDII plug. just want to see if i can even make it work and keep the alarm it has on it or if i would have to pick one. Thanks in advance!
