I see these performance chips advertised that can increase HP up to 35 hp. Has anyone placed these chips in their car? What results have you experienced? Do they hurt the car in anyway? Do they void the warranty?
Well first off it says don't put them on turbo or diesel cars so I would say stay away... Plus I've never heard of them. For the wrx, either get a COBB Accessport or Opensource Tunes from reputable tuners (XPT, local shops)
yea just looking at that website, they also sell electric superchargers and the turbo muffler sound thing. i would stay away from this company because it all seems like bullshit. there are hundreds of subaru people who run either cobb accessport or opensource or utec. check those three out if you want to see true performance gains
