Also, FWIW, I dropped 9 degrees of KR and then dropped from a 3.5" pulley down to a 3.3" pulley and am still seeing roughly 0* KR... Have not had an IC setup on mine personally, but I can say that E85 is awesome. I can see it as being one of the best mods for these GTPs if you are on a budget. You could easily take a stock one or one with simple/minor mods (like mine) and run E85 and drop several pulley sizes I believe.
