Was looking at my average MPG before and after the Garrett chip upgrade and I got on average 18.97 mpg and now I average 20.65 mpg.

Assuming 12K miles / year and $2.16 / gallon (today's fill-up price) -- I'll save $111.16 just in gas which should help offset track fees.

Driving style is about the same -- if not more aggressive since the upgrade.

Any similar experiences?

You work for GEICO?

Stoichiometric ratio is 14.7:1, that is for every 1lbs of fuel, 14.7lbs of air is burned also. with the GIAC, less fuel is being sent into the mix, blah blah blah, this goes on forever.. Look up stoichiometric on google, you'll learn a lot.

GIAC was a mile or two better mileage, but when i went from giac to neuspeed k04, mileage got better by 3mpg easy! pretty cool.

Nice guy. He showed up for a local Dyno day here in Phoenix. Thought it was purty kewl of him to hang out & answer questions. Looked like they were having a hell of a time trying to get a 225 TT to upload the software.

I think that's the clear advatnage of the 225 with the 6th gear.
180 w/ Revo. I got 23mpg before, 20 mpg now.

I'll get 37-40 mpg on the highway. Ive gotten 540 miles on a tank one time.. Out to Arizona and back on one tank. I actually get the best fuel mileage at 82 mph, with the tach reading about 3300rpm or so.
If I start kicking it down though, I'll get terrible gas mileage. Talking 200 miles per/tank or less. Oh hell, its just gas.

for your reference, my stock 180 FWD gets me about 28mpg..
