Your MPG Improvement with Wong Chip?
 

It's well documented that Steve's chip will improve MPG, among other things.

For those who have chipped, what has your mileage improvement been? With gas prices north of $3/gal we're talking real money here!

Thanks!

I'm up from about 16mpg to 19-20 for my mix of mostly around town, some highway in my 1985 with the chip configured for stock exhaust. Seems to be around 22-24 on the highway.

I am seeing a decent increase as well on my first tank of gas as it went up about 4-5 mpg highway.

Time will tell...

Never checked mileage prior to the new chip, but getting a consistent 22 mpg with SW Chip (about 50/50 city-hwy mix). Feels like only a slight improvement in gas mileage, BUT I probably put my foot in it a lot more now with the chip installed :). Can't help it!
