Ok well my car has a mild heads cam package (read my signature) and am running a 42lb injector and here that it is to much and wastes fuel. I Dynoed 420 rwhp and plan on a 100-125 shot later wet set up off the fuel rail. So what injector size can I go with? 32lb? 36?
Thanks

42 lbs aren't too big. You need to have them tuned and they will work fine.

with those power numbers 42lb will be fat at the bottom end.you should run a 42lb at 58psi.

I don't really understand what ur saying? I don't have nitrous yet but plan on later. The only reason why I made this post is because I was running ethanol before that's why I had the 42lbs and now switched back to gas do to availability of ethanol where I'm at , and my gas mileage is around the same as ethanol? Ex. I had 28lb injectors be fore the ethanol tune and was getting around 23mpg. And now with the 42lbs I average 16-17 mph. Just want to know if a smaller injector will give me my fuel mileage back . Thanks

36# or 37# somewhere around there will be perfectly fine. 42# is overkill unless you plan on making another 100hp in the future.
