spark cutout and wastegate issues on new turbo setup
 
91 miata 1.6 running megasquirt pnpg2 v1.3
this is my first time driving my miata with my turbo set up and i was getting spark cutout around 4500-5500 rpm i gapped my plugs down to .030 and still does it. was wanting to know if my ignition table and fuel tables were ok. my external wastegate is set to 7psi but isnt keeping it there and i saw it go to around 13psi before i let off. car has rx8 injectors on it and is running a decent AFR. the external wastegate has 2 vacuum lines on it not sure what one should be getting hooked to. im sorry for the nooby questions i just dont want anything bad to happen any help would be great.
