your still injecting the same amout of fuel just sooener ... but yes it should slightly reduce smoke.

AFC tuning will make more difference in smoke control than timing will

It also depends on how you drive your truck as to how much it will hold with stock bolts. Im one that wont go past 16.5 with stock bolts but i did a truck with stock bolts to 23 and it lasted until he got rid of the truck and when he got rid of it the kid didnt have it for the weekend and it got trashed. It will greatly effect your spool time with a bigger charger and poorly tuned afc, and this said truck hated cold weather by the way.

heard that well i just want a little more power with this nv4500 comin im goin to 19!!! how much does it cost to get a pump flowed if i take one off and take it to them to so i cant get a little more fuel with timing at once

depends on whom does it ... round about $300 ish for balanced and flowed

so i might as well go big huh

or just wait till i get the money to go big and get a bigger turbo

if your gonna do it, now while the pump is off is the best time. you will always be able to cut fuel via fuel plate pos for what ever charger you end up with

the problem with adding too much timing is that the p7100 has fixed timing, and even 12 degrees is alot of timing for idle speed so its a trade off, it kinda sucks really. a Duramax or any modern diesel would idle in the negative timing numbers and then go all the way up in the 30s(on a hot tune) when running.

It did to a certain point.

i can adjust idling if thats what you mean and good deal to reduce it after u roll smoke a while u just want power or i do

Are there any down sides to adjusting the timing? I heard that it risks the pistons...unsure though...:pca1:
