I am new to the Subaru world and have a 2011 WRX that I purchased back in November. I bought it will an invidia CDP and SPT CBE with a custom stage 2 tune. I know I if I put an intake on I will have to get it retuned. I dont need to put a SRI on but I kind of want too. Will I lose a lot if I go to a Cobb Stage 2 Tune from the tune I am running now? I am running 299 hp and 336 ft/tq and around 17-18 psi peak. This may be a noob question I know but I am just curious. It will help me make the choice if i want to do this or not.
