Note 1:
With this code, normally when you flip your vehicle and it has to put you right side up, it takes away all of your items/weapons, with this code, it will give you the same that you 'started with'. Also, its recommended to use the items in 'order'. So I wouldnt put an item in slot 8 without putting one in slot 7 first.
