06legsleeper Posted February 20, 2013 Author Share Posted February 20, 2013 yeah i knew that its not a good idea to run 91 on a 93 tune , unless your really stuck without your ap , or other situations... i loaded my 91 map with a tank of 93 in it , seems the cars runs smoother , prob go back to 93 when the spring comes... better gas .. thanks Link to comment Share on other sites More sharing options...
stuck686 Posted February 20, 2013 Share Posted February 20, 2013 ive read only use 93 on a 91 map. since 91 prob isnt 91 in reality. Link to comment Share on other sites More sharing options...
