First- please advise if this is in tyhe wrong place I know there is a forum on these vehicles- but I thought this might be best in General 1st- I’m a past mechanic- have always believed “it’s how you drive to get mileage” and I’ve always been open getting better performance/mileage out of any vehicle- if you are willing to learn my case- I have 2 4WD Escapes- both allmost exactly the same 2008 and 2009 V6′s my 2009 gets 2.8 mpg better than my 2008 you have to realize- I drive like an old man- know where any given vehicle, speed, will perform best- I also believe in the vacuum guage- or such- to tell where a vehicle is crusing So- after 2 months of reviewing- have ordered a performance chip supposedly it can be pulled out and installed with no problems so- I’m going to install it first in the 2008 Escape first- I have my baseline mileage of both vehicles- I have documentation of the average, town, country, hyway- and a 343 mile drive where bopth vehicles were driven the same I choose this performance chip- based on what I believe is a fair and ballanced review- I ordered it today- will be willing to write here on how easy and formative the instructions are- the product in itself- 1- what I experienced 2-what my goals were 3-when and where did I notice anything 4-all arround driving for the 1st 200 miles 5- what did I notice different 6- on the hyway at what I believe is ultimate cruising speed- what did I notice 7- based on my baseline mpg test before- what is it now- and since the 2009 is getting better gas mileage- what will this test tell on both vehicles
