So my brother in law and very good friend is buying a 2008 mazda speed 3 and is already started talking smack I have an '07 Wrx limited at Cobb stage 2. He will pretty much be stage 1 off the bat and then probably stage 2 soon after that...Assuming I'm the better driver who will win in a friendly race (1/4 mile and or highway). Also...If i'm running the stage 2 map from cobb which is 16 psi peak...Is it possible to increase the boost 1 more psi and keep the stage 2 map or is it a must to get a protune at that point? (how much money on average is a protune?)
The numbers on the speed 3 are impressive let's talk about why we love subaru's more!
