G day all I'm about to spend 4000 plus on a vf 34 turbo, tune, fuel pump at Maxinum Motorsport. I have a 07 Wrx with 3 inch cat back exhaust and blow off valve. It's the first time I've spent this much money on any performance mods on any car I've had and am just feeling a bit nervous parting with my hard earned cash. I has told to expect approx 220 hp at the wheels. What Im looking for is feedback on these mods. Am I wasting money 220 hp doesn't seem like a lot of power for such a high dollar.
