NO, it is over injectored for sure. I got these new for $200 and was thinking they would have me covered and then some, might have to plumb a direct port 300 shot to justify them lol! Knowing what I know now I would've gotten 60lb versions of the same injectors. Oh well ive gotten these to idle fine for now and will probably keep my eyes peeled for some 60 lb'ers in the future. These are good for probably 900hp N/A and im no where near that.
