]hi everybody just bought myself a 03 plate td4 at Christmas and i got a 3 month warranty on the engine and gearbox up to now i am impressed with it apart from a few niggles like, getting a shower through the sun roof when its raining but anyway i,ll get to my question i have bought a synergy2+ tuning module and i want to know if the are easily fitted my days of messing with car engines are almos over. although i am mechanically minded, cars just had plugs and points in them the last time i looked at an enginr . it goes on about something about a bosch maf and a pierburgh maf.can i tell which one i have or do i just take it to the garage and have it fitted thanks :dance
