Looking for a new tuner located in Socal that isn't trying to rape for work. Know anyone who can perform installs (2 step & antilag) as well as tune custom maps and make sure car is burning fuel efficiency?

Thanks for any help you can provide!

No need to pay a tuner to custom tune maps with a JB4 ... Just datalog and post it on forums.
BMS can give you advice on what you can do to get more power
