there isnt really any mods to the engine just a miltek cat-back i want the manifold and sport cat but pumaspeed said they only have a few left and they arnt making anymore dont no if its true but if it is then im stumped as id need about £700 sharpish, if i was to buy the power boost valve i would get a prefesional to fit it and set it up, im not trying to gain big bhp just quicker acceloration, induction kit is going on soon, i looked at a remap but im only going to gain around 8hp for £250 didnt think it was worth it i would if i did everything else, just need to decide about the boost valve if its no good i would rather use the £100 else where
