I know that there are some threads on this but , is actually someone rolling with SDI cam in TDI PD ? I am looking to install a 2.0 GOLF 5 SDI cam into 1.9 AVF soon . I previously owned a Seat Leon 1.9 ASV which ended up with 240HP . Among alot of mods , i used a SDI cam into it . Because i knew my car , the difference was immediately , i noticed a stronger exhaust sound , and increse in torque , starting from 1900RPM car was noticeably more aggresive and rpm went up quicker . I wish if someone installed SDI into PD can say something about how he felt the car after . Cheers .
