185mm pulley/tune, shorty headers, and res delete.

Not bad for a 440hp car IMO.
Your numbers are pretty close to most of us C32 owners. But I can average a smidge bit more than 20 combined.

Just curious, how did you come up with 440 BHP? Do you have a dyno reading for RWHP?

I got a bit of a lead foot, but it's hard not to have one with that much power. Calculated that figure with the most accurate butt dyno in the world!

Figured, 70hp from the 185mm/tune and then another 20hp from the shorty headers.

Just bought an '04 C32 yesterday and drove 4 hours on the interstate to take her home. Drove ~70-85 MPH during the trip. Onboard computer showed 26.1 MPG but actual calculation came out to 24.1 MPG. Car is all stock, so a little surprised MPG discrepancy was big, but then again not too surprise since these cars are old

Is that as calculated by the trip computer or using old fashion manual calculation? In my case, trip computer was more generous in reporting MPG.

City driving I get ~20 mpg; Highway I get 24-27 mpg depending on speed; as reported by the computer. Mashing the gas frequently drops these by 5 mpg.
2003 C32 with 125K miles; only engine mod is K&N filters.

I rarely get on it BTW. It has an LET 185mm pulley/LET tune, FWIW.

It's kind of sad to think my other car gets better gas mileage...
supercharged engines run a rich fuel mixture to help keep the cylinders cooler just a fact of life it’s not going to get great fuel mileage on a recent 450 mike trip I averaged 24 miles per gallon on the last leg of the trip I got close to 27 miles per gallon with the cruise set at 75mph late night cool air and slight mist in the air 85 miles of that I never turned off the cruise or even changed lanes on the other hand around town it eats gas like a fat lady at a buffet but I should measure it by ounces of rubber per mile
