Re: 33 Mpg...... (corvette0096)
On my many trips to the sunshine state, I average about 29.6 mpg.
I did see a best of 32 on one segment(drove about 450 miles before stopping).

Re: 33 Mpg...... (corvette0096)
The miles per gallon figure is based on computed value using stock injectors and stock fuel pressure. If one changes to a larger injector, pulse times will decrease during cruise closed loop and the puter figures the flow rate using pulse times for smaller injectors. This assumes stock chip. Not sure if your chip was changed to reflect this. Have heard increase of 2-4 mph when changing injector size without changing programming. Still, the C4 can turn some really good fuel numbers. Fun cars.

Stock my car was getting around 32 mpg at around 75 mph in 6th.
After I stroked it and super rammed it, it dropped down to about 28.
I had a custom Fastchips chip burned for me.
Now that I added the 30 # injectors and had to switch back to stock chip, cuz the custom chip wasn't running the car properly.....it said I'm getting close to 40 mpg. WTF? I thought it was kinda funny reading that high. Anyways, I'm gonna get a new chip burned for me soon.
All mpgs were recorded in 6th gear at 75 mph @ 1700 RPM.
