Hi, maybe you have another tip to make my KX in the Audi Coupe even stronger. The original part doesn’t go for a meter. I’ve already done the following: -Two-toothed trouser tube + cracker -Züdung von 6 to 12° vor OT -Injection system of 2.3 liter -Kat empty and 50 tube through -K&N filter use -Better cold air supply -More air in the tires 😉 Now it goes quite well, until 120 a 16V from the Golf 3 has no chance, until 100 it is as fast as a BMW 328!!! No, I have no I have only certain sections/test tracks in which I compare different cars from friends! Is there anything else that fits from other 5 cylinders to make it better. Except Turbo, where I would have one, only the conversion is too expensive for me. Perhaps camshaft, there is something else, where? Thanks already for your opinion and help! Greeting René
