I'll put it this way..I'm running 60's, Injen intake, full engine exhaust and a very very mild tune, and I see 34.6 MPG in the city, on 91 octane(the closest to premium they have in Kansas)

With the proper tune you can have close to stock or better gas milage

They deliver the amount that is needed, just like the stockers do.. Only they can dump it when needed...

Well you can get anywhere where I live by a short jaunt on the highway, so maybe it plays into it, but why in the hell would I lie about my MPG? Even if I were going to lie, why would I choose some obscure number number like 34.6. Yes, when driving around town I don't beat the hell out of my car. I am one of 4 SC's in my area, and the only black one...Even the tech at the dealer where I got my oil change last week said he's worked on all the SC's in Wichita, and mine is the most extensively modified. Needless to say I figure its easy to find my car, and the cops are plenty, with a 0 tolerance policy on speeding. If anyone wants to see my DIC readout you're more than welcome to it.

The 60lb injectors, tuned correctly, will only inject the amount of fuel needed to get the desired AFR. You could put 60lb injectors into a completely stock car, tune the computer to know that they are 60lb injectors, and it shouldn't be any differently at all from stock. Your just going to see a max dutcy cycle of about 50% hehe.

Most people that put 60lb injectors into their car don't drive it for economy though. I used to get 26-28mpg when I was stock. Now I run between 19-20mpg. I normally accelerate at about 10PSI - 12.5 PSI of boost now though. Immagine dumping the equivalent fuel of running the car stock WOT, to normally accelerate... But it's more fun .

On the highway I average 38-40mpg @ 80mph with my 60lb injectors. It's all in the tune.

1000cc injectors are ~ the same as 65# injectors.

34 in the city? You must shift at 1500rpm

I see 34-36mpg highway (70mph cruise) and about 28-32mpg in the city. it's pretty easy to get better gas mileage than stock with a good tune.
