Its totally worth it if you're wanting more response and more top and bottom end. Super easy to do. They only thing we really recommend is sticking with the minimum octane requirements. Its a minimum of 91 for stage one and a minimum of 93 for stage 2. Some areas are limited on 93, so it just comes down to what you want and the gas you have available around you. Plus, you get a little discount from me for being a member on here. If you decide to pull the trigger, shoot me a PM and I'll get you whatever the weekly member code is.
