well for me with almost the same modes: AEM cold air intake and TSUDO catback exhaust, i ran a 15.9 =/ Very shitty times. I had my power steering and AC belt still on the car with stock timing set at 16 degrees.
If u wanna run a faster time, remove ur PS and AC belts, go to autozone get a timing light and advace your timing to about 18 degrees
heres a write up i did on how to advance your timing

but if u r gonna advance the timing, u need to move the distributor towards the firewall not towards the front of the car(moving to the front retards the timing). U need to line up the white mark on the crank pulley that is closest to the front of the vehicle with the timing mark on the timinign belt cover
