Here's the equation:

RV6 pcd's (used) + j pipe + true dual exhaust X check engine codes (P0420 + P0430) = 25 mpg

I was averaging 20-21 prior to this. I drive 90% city.

 

02 senors arent doing their job.

so, if you're going by the MID, it's false.


if you're doing it by hand and coming out with those results, than great find!

 

I go by trip meter/gallons purchased. Will have to wait for next fill up to report again because I pulled the battery cable last night to swap out my sub amp.

 

Follow up: averaged 25.4 mpg this last tank but also had a 150 mile highway trip in there.

On a side note, plugged in hondata Saturday night and now the rpm's at 70 mph are no longer at mind numbing 2500 rpm drone but rather slightly past 2k.
