Have had a lot of fun with Leo's so far but the backfiring my be gradually give me the wanker status.
So I been thinking about the sas plates, the options I have according to preference
Map is made up with akar and pc111 merge

Turn on on tune Ecu ( don't know what the drawback is?)
Make up a carbon copy spacer plate out of some sort of thin zinc tin ( don't know how much vacuumed pressure is on the system plus different metals together)
Do the marble job (find the right marble and where to put it)
Remove the sas system ( last option to do anything with the tank bolt)

So what's my best option?
