what boost should i run with setup?

too many varibles. log it and you'll find out. i ran over 20 psi on pump gas with my evo III and 450s. some people can't do that with 680s, its all tuning.

That is very impressive

i never looked at my injector duty cycle but it would have been rediculous i bet. i always tuned for less than 6 counts of knock regardless of temperature. just focus on tuning the car start at 12 or 15lbs and just keep increasing and retuning 1psi at a time.

oh and this was all done on a maf-t with no afc

Pick up a logger so you aren't playing a guessing game.

thanx guys i will get a logger and learn how to use it a/s/a/p

i cant understan how so many people start modding without having a logger.

Word....Even worse is that they come here asking questions about how to drive their own car-----Why people think you can drive your car hard w/out tuning makes no sense to me...Buying an safc won't do anything unless you actuallly put it to use...

For now, you should be fine at ~15psi, but if you creep or spike, tone it down...w/ a 190 $ 510's, I doubt you are running super rich at 15psi, but you could be running lean, so be careful..knock is not fun

as much as possible
