Thanks. I have tried it and it is very good but it is not as close to the stock ls7 engine. It has less torque and the curves are different. The rpm limiter is much higher. It gives me the feeling of a Nascar engine. The sound is very similar to Nascar engine.
You won't believe it but i created the engine from the engine you used in the Coquette Z5 (stock one). Excellent mod love that coquette. I hope you do a coquette z6.
