ill speak on my behalf....being that my car is on a stock ecu with no check engine lights or idling problems. there should be no reason why u cant use the car daily. but be honest with yourself. will you still drive it as if it were still stock? its a very hard thing to do. im constantly on the gas letting the wastegate rip. its fun. the whole car takes on a new attitude. as far as your long commutes....its hard to say. which ever kit you go with just make sure you get it installed properly. and keep the oil changes as religious as possible.
