i addvance my timing to 12-13 degrees from stock i think its about 8-10. i also by pass my coolant lines from the stock egr spacer when i was messing with the timing, and i gain about close to 4 tenths in the quarter.
You will have to play with your timeing to get it where your car likes it best. Every car is different, so advance it 2* each time til you feel the car running its best. Bet place to do it would be a track. Us ethe search button and you will find a lot of tips Good Luck

some cars want more timing some want less...im and currently running my timing at 16* with middle grade pump gas and no pinging....no pinging is the main thing, you do not want any ping but do a search and find a lot of info
there are coolant lines that run to the egr, so it heats up the egr, throttle body, and intake manifold when using in the winter. all i did was put screw caps on the egr nipple things, and connected the tubes with a 2 way tube connector.
the other school of thought on the coolant lines to the EGR: the coolant actually cools the TB/EGR down. what is heating up the intake - 600*F EGR gasses or 200* coolant? the coolant cools the inlet. reducing inlet temps really helps make HP. at the track, i would rather ice the intake myself.
i would also note that there is a point of diminishing returns with timing. one can advance to a point where HP is being lost, but before detonation. so i dont necessarily run on the ragged edge of detonation (having leeway is nice anyhow).

i did this because i use a intake manifold spacer, with having the coolant lines still in the egr plate with the intake spacer, it kind of defeats the perpose of having a intake spacer-which is to also lower the temp. my upper intake manifold is about cool to the touch.
