Hello all, I have been looking around the internet to find more info on engine upgrades for my 3.2 engine. Rightnow I have not been able to find any upgrades at all, please I need help. I think the engine is ok, but since I have bullet proofed my Q5 ( I live in Colombia ) I really feel the car slow on step climbs. The only thing that has helped a little is the exhaust caractere that I recently installed, but I need more. Please help me out thanks
