I've read that a mbc and bov and k & n filters are the way to go but I've also read going with a unichip and exhaust.
Which exhaust sounds the closest to stock i.e the least noisy?
If I go unichip then is a mbc still necessary?
Uppipe and boost controller are what I recommend as the very first mods. Unichip is also a great mod. A turbo upgrade should be on your list also although is 50 HP is all you want you can probably get there without changing the turbo if you really tried.
