If I advance or retard the initial timing on my car, will it offset the timing on a custom chip? Reason I ask is because I am running 14.6 at 92 mph. My mods are in my sig and I know I am missing power somewhere. But when I dynoed my car it is making 200 hp and 250 torque. Also if I mess with initial timing, wont it mess with the air/fuel ratio? My ratio is dead on. Thanks in advance.

 

Adding more initial timing will just add that much more timing through the entire curve. IE - add 2* more inital, you'll have 2* more at 2000, 2* more at 3500....

 

so would you advise me to mess with the initial timing or no?
