OP you are close enough to Synergy. i recommend you tow that truck up here and have Rick tune it. i know there are alot of good tuners in the Bakersfield area but no one can hold a candle to what he can do. dyno tune will set you back 600 bucks and he can do it in a day. make and appointment get her done and thank me later. but stop by my place when you are done.
