mmmmk so the car is running very nice right now, running 20lbs of boost and it feels strong. on the wideband at WOT I am seeing mid 10's, base timing is set (factory) and the cam gear is at zero. I know it is still kinda rich but I think I might be able to tune it in a little more, it does not really like it when I pull the fp back anymore, it creats a low throttle cruise stumble. I do not want to get into a whats right and whats wrong EGT argument so lets say at WOT I am reading 1550. So when I advance the timing what can I expect to see? What will happen to EGT? what happens to the boost/torque curve? will it change my A/F any? If I retard it does the direct opposite happen to each of the above mentioned? I think I will be putting it on the dyno soon and I want to know what directions to go on adjustment. What about base timing? I know it is hard to compare one set-up to another because there are soooo many different routes people take, but I would like to get a better understanding of the little adjustments that can be made and their affect on the engine. I am not looking for an all out race set-up. I am looking for a fun, pretty quick well tuned (standalone aside) engine. Thanks guys and I look forward to your input.
