do the oem ECU's eva pack up like, stop werkin n tha ... cant imagine much wrong goin with a microchip. it's just hav bin told to replace it (by sum vauxhall mechanic doin a foreigner) n he sed they cost like 600 quid !!!
So if I were to remove the Superchip in my ECU, and replace with the standard item,would I see any performance gains? (Seems a rather messed up approach to modifying, but hell, if there's an improvement to be had I'll do it lmao )
