im getting xmas tree effect over 7k revs in 2nd gear and above, im thinking about upping the fuelk pressure doesnt seem to matter whether im running 1,3 bar or less than a bar still does it ,any ideas?
Im sure when i first got the car it was running 4 bar fuel pressure on idle, it's now at 3.5 bar, is it normal for it to decrease over time ?
Could it be leaning out at this RPM ?
