I am cheap to but once you get it done and over with its honestly worth it and i think you would get quite a bit more then a little performance boost.
Why dont you have a giles pump on your car yet??? I recieved a built pump and set of rebuilt 155 bar injectors and all i have to say is wow. Giles did his first 12 mm pump for me and i dont think i could ask for anything better. VARY SATISFIED! with a factory pump with the fuel screw turned right up on my car it was only just barely beating 2.2 caveliers :cry: so i patiently waited about a week and through the pump in on the weekend and all i have to say is wow. It has gotta be about 3 times faster then it was before and there is no exhaust smoke under boost.even under no boost and punch it there is only a haze. I only have a 1.6 and i have never felt so much off boost torque (from a 1.6).... listen to me bable like a little school boy. :lol: anyways i just had to vent a little bit cause i am so excited about it.
