I got my 2010 WRX hatch back in march along with an extended warranty. So far, I've only tinted my windows, changed speakers, new headunit, shiftknob, tail light overlay. So its all cosmetics, now I'm itching to modify it for speed.
I will have to cancel my extended warranty, which is about $1400 back in my pockets hopefully after pro-rated. I want to pick up a Invidia V4 Catted DP, Invidia Q300, and AP ($1500). I checked the price for opensource at a tuner, its about $450. So if I just use the AP pre-loaded maps for Stage 2 is that comparable? I am not mechanically inclined or want to try to buy a tantrix cable to run the opensource map myself.
