Hi guys, i have just had my car tuned again with the pwoer fc in it, it now makes 246rwkw on 14psi, however it now has a lot of lag, and feels like it's getting slower and slower and the engine light comes on at 7krpm. Can anyone recomend a really good tuner in melbourne? I have taken it abck ot the guy and he doesn't know what to do. Any help would be greatly appreciated. THanks Mark
