Hi, just had a good run of the car in the garden. I have tuned the HSN needle a little but still had acceleration problems. I started tuning the LSN and this improved the acceleration does it matter that I've tuned LSN more than the HSN? Or is HSN supposed to be fully tuned before I tune the LSN? Also at one point the car started moving forward by itself with the radio equipment on, i turned off the equipment and it stopped moving forward. What was that about? Car is absolutely covered in mud now!!
