I don't know how to check if the car is tuned or not , it has quite a bit of mods : Whoosh motor sports hybrid turbo, Whoosh motor sports track manifold, Whoosh motor sports v2 front mount core, Mishimoto hot and cold side inter-cooler pipes, Whoosh Motorsport 3” down-pipe, Miltek cat-back non res E=exhaust, Turbosmart em2 BOV, Turbosmart 14 psi waste-gate . When I get on it it feels flat like the car starts to jerk a bit as if it's not getting enough fuel . I ordered cobb accessport shud be arriving in few days . I wanted to ask previous owner which tune was he running on this etc
