oh and as an after thought. dont be to critical if the banks are not equal when you look. they seldom are and you will find that they very rarely are so. just as long as they are near enough +5 to -5 you should be ok. dont know how much you are into this lpg tune on the stag system but if you have a scanner that records live data you can plug in to your diagnostic port on the car and it should give you the temp of the engine plus the rpm when the fault occurred . this should then guide you as to whether the lpg is too weak upon changeover. do whatever is best for you and good luck !! ......
