cobb doesn't have a 93 oct map for ms cai and down pipe and cat back, only 91. when I upgrade my ic, then there is a 93 oct map, they sugg the map I am now running until I upgrade.
did you ever hear of a correction factor? these are corrected readings, so no variables involved. also peak numbers are not the total gains, the midrange increased alittle over fifty hp and top-end past 6200 almost 100 hp.
My '09 Speed 3 rang up 290 hp, 308 tq!
