they have the cobb AP units that can change the maps on stock ECUs. 2 of my friends have them, 1 for a 2007 mazdasped 3 and a 2007 wrx. of course my car is still faster than theirs but it would be nice if we had something that convenient! is there anything that i can use besides running my out-of-date PFS PMC that is an inexpensive, safe alternative?? oh and im anti-powerfc so dont suggest it plz. thanks!
