Improved gas millage

[John S. Murbach]

Tried a product that was just two wire hook up to the IAT/MAF sensor, after 100 mile break in my white lable went from 21.8 mpg highway at 77 mph average to 24.9 mpg at 82mph average on the same 165 mile trip. On the street went from 16.9 to 20.1 with normal and alittle Saleen performance driving. Will be going to check on Dyno (second trip there) during first week of April. For product states it increases rear wheel HP any where from 10-30 Hp. Check with app Road Race and before 0-60 4.34 now 4.17 . Will post results once HP change when I have it. But the gas savings was a pleasent surprise for around $75 and that includes shipping. Check it out at www.gfchips.com. In AZ the premiun price $3.54 it will take about 8-10 fill ups to pay for itself. Big improvement at low street speeds in higher gears more of a smooth ride. Check it out

Interesting, but not sure how something like this would work on a supercharged car which is already re-tuned...

[John S. Murbach]

That is a good quetion and the answer is in the ecm module a super chip may do it but the add on chages the 12-1 steady ratio to your driving style, Super chips that are tuned for super charger may have a fix ratio thn it will help but if you have to have a hand program to switch from street to race modes then the chip would be change by stopping and hand tuning each time this chip change the ratio with the air flow /driving sytle. It 100% refundable if there no change and it can be added and removed with little effort.
