I'm new to the SRT-10 family so I'm trying to figure out some of the mods etc. My question is in my state we dont' have higher than 91 oct so what type of PCM upgrade would be best for my '05 RC? No mods done yet but several planned if that affects PCM choice. I've only had the truck a few months so any advice/tips or reference to threads on the topic would be awesome! :rock: :bandit: :thrasher:
