Stupid question, but hows your gas mileage with all those bolt-ons? I probably get low 20's right now and I'd love to get upper 20's, however I can.

 

Better than it was stock mainly due to the tune. The stock tune is very rich simply for safety. We targeted a ideal AFR and leaned it out. My last fill up I got 20 more miles out of a tank than I usually do. Aside from that just don't always have your foot in it.

 

Upper 20's MPG - EVO

Does not compute.

You would literally have to shift at like 2k everywhere to even come close to that, and never go over 50 in a GSR or 60 in an MR.

I didn't buy this car for fuel efficiency, anyone that did is fooling themselves.

This thing gets WORSE gas mileage than my 2004 Cobra that had a V8 and a supercharger.

ROFL

 

Yeah they're definitely about smiles per gallon, not miles per gallon. The only thing I can think of making any kind of serious increase would be to change the final drive ratio so the gears are a little longer
