hi i was thinking of buying the eurocharged pulley this week but im a bit short for buying the tune and the remote cable. is it okay the just use the pulley for a while and will it give a noticable gain ?. then in a few months i was going to go to a rolling road and have them custom map the car because this surely if the safest way, has anyone else done it this way or has everyone just bought the complete pakage from eurocharged . every car is different and remote tuning can be a bit iffy to say the least thats why i would prefer a custom map
