New mods!
Yes, recently we decided to cutoff the power-steering belt to minimise engine hp loss. Then, we removed the parking brake switch so the DRL doesn't start when we lower the hand brake. (Only little problem, parking brake light is always on
)
With these two mods, we recently achieved 3.5 LHK (67.4 MPG us) when returning from quebec city and from Béthanie. This is close to our next goal : 70 MPG us (3.36 LHK) !
