Ok this is my first thread here and I am looking for help to ecomodding my new front splitter. First off I have been on this site for a while but now I have something new to challenge people. I put on a splitter to my passat b5.5 2005 1.9tdi and it is one foot in from either side of the car and am looking to improve it. I don't real do a - b - a testing however I monitor the fuel gauge and every now and again do a test from the reserve light to 24 litres of fuel to reserve light and have got 65mpg imperial but now going hard at it. I will add photos once I get the required posts. any help appreciated
