I would really recommend you do some research on your solenoids and look into changing them to wizards stuff as they would have been heavily responsible for your failure with the constant lean hit they give every gear change and activation
Their stuff really is worth the extra few quid and you will make more power from the same amount of nitrous or the same power from less gas and nitrous ain't cheap now
I'm gutted I sold my kit off the Bmw it was so much fun
