Hi Matt
reason I only put a small amount of fuel, at most half a tank is financial, cant afford more, as I drive about 35 miles a day everyday I kinda get a feel for the difference a mod makes, sorta driving by the seat of me pants!!!!
I know it is not very scientific, but having no way of monitoring the performance via scan guage or other means, engine is a mech injection deisel, I have to try and take what feed back I can from where I can.......
I would love to have the money to get a 300+ mile load of fuel, but that is near on 60 GBP and budgets dont get that far
Hence the gaffer tape and cardboard
Enjoy
