are there any significant gains of 1600cc injectors that i can't obtain with 1200's or even 1000's? For those that know, i'm shooting for 750ish whp, on a turbo the size of a 40r(ish) lol. i want to get on the highway cruising out of boost at least 15mpg and city (not pushin it) at least 8. those are very low figures but what do you guys think?

 

IMO you would be fine with 1200"s, to me the rest might be a little overkill...
