i was wondering about spark tables today. i'm going to have the car dyno tuned by speed inc so it will be optimized for my current setup, which is basically a cam as my only major power upgrade. now, with this all said and done, will i have to cange the spark/timing tables again if i would get some ported (lets say LE2) heads for my car later on? I know fuel curves will need to be changed and optimized again, but will the timing tables need to be altered any, assuming i run the excact same compression? (11:1 btw)??? thanks
