With regards to the re-flashing well the company I"m buying the flash from does custom tunes... I'm buying three (87 / 89 Octane Performance and 93 Octane Race) I'll run with the 93 race whilst gas is so cheap.... anyways back on point the company will update my custom tunes FOC with basic modifications, but if I do anything big then there is a $50 charge for writing a new tune, if I did what you suggested to my exhaust it should be a free change....
Oh and check out first post for Strut brace photos
