what boost level? would me set up take it?

I'm sending a set of 550cc suby's to witchhunter to be drilled and flowed to 800cc, fairly cheap to do also, considering I got the injectors for less than a hundred bucks.

^ that doesnt sound like a bad deal, wonder how much dsm 550s can be drilled and flowed to this might be a good idea for others whom are looking for good cheap higher flowing injectors.

and as far as boost levels, what is your setup consisting of again?

you will need to run over 20psi to hit 400whp.

what do you think i would make running 19 high and 12 low?
and what if i were to only use the stock gtir injectors what kinda power would i expect...

well for one the injectors might limit you on the ammount of power you are able to make, keep in mind with more boost more fuel is needed and if you max out the injectors your in turn going to be limited on boost. at least until you get bigger injectors.

high 19 i feel a good 375ish give or take and 12 probably low 300s to high 200 give or take, this also depends on the tune & where the injectors give out at.
