Looking for an original IS20 upgrade charger providing as twice as much HP than original because the DSG, Haldex and engine can cope with about 450HP easily. Some upgrade companies provide good big IS38 chargers (TTE, TTH, PnP, Loba, etc.). I am interested in an IS20 originally looking charger. What about this PnP LM440 (IS20) put into a bigger SEAT. Worth the money?
