Has anyone seen a significant increase in MPG after intake or exhaust?

Just wondering if anyone has documented a consistent increase in GPM after your CAI or exhaust install.

I installed my injen CAI last week and I have only driven the car 50miles or so since then. I reset my computer during the install so I am sure it isn't running as efficient as it potentially could be yet. I am currently getting the same gas mileage I was before, right around 22mpg with mostly city driving. I used the on board computer for my GPM calculations in case anyone was wondering.

I had the same questions before my CAI install. I was getting 26~27 before and I'm still getting exactly the same now (about 3,500 miles later).

I'm not sure about the exhaust install though. Some guys here suggested that I might lose a little bit of mileage with exhaust mod. I haven't done an exhaust mod yet. Gotta wait until after Christmas to do anymore to the car.

ease up on the throttle then, alot of people lost mileage because they mash the throttle more to hear that beutiful sound of vtec

I just put on intake and haven't gone to fill my tank yet. Once I fill it up I'll let you know what the mileage is. Before I was getting 18-19 ALL city and hills etc. Pretty crappy for a Honda I must say.

I know that theoretically it should increase gas mileage and I am aware of the previous threads. What I have yet to find (Well before kramer2k posted ) is concrete before and after MPG with the driver driving the same before and after.
