i own a 2006 wrx, it has sti springs, a cobb downpipe and cat exhaust. i just ordered AP V 2 that will come on friday, what maps should i load? i live in Idaho, elevation 2800 and my car has been running on 91 octane, im not sure who sells 93 ?
is there a big performance jump from 91 to 93 ? and if the AP maps your car to run on 93, what are the gains?
also, what gains should i expect on my car? HP Torque?
Check out Cobbs site and map notes. If you only have 91 in your area, you will run the Stage 2 91 OCT. Any number given is a guess, so again check out their site. It varies from car to car, they dont react alike even with the same exact mods in the same area on the same year car. Running 93 might give you more power, but if you can part with the extra coin for a few extra ponies, thats your call.
