i have been throwing the idea of going with one of the tourqued performance maps. i went on the site just a minute ago and read it works with 91 or 93 octane. in theory im thinking my cobb 93 oct map will yield more power due to more timing on the higher octane fuel. if i run a map for either 91 or 93 its going to make my extra 2 octane just a safety net. is this worth the 85$ for it over cobb?
