Need to know the stock pressure so I know how much I can bump the fuel pressure for more gas + more boost = more power

I cancel the last dyno and have a new one this sunday , I will let u know the results and try to get a evoscan log but am deffo lean , pluggs are white , manifold its glowing red , car misfire on cold start . I changed pluggs and gap them , bpr7es 0.7 gap . Changed fuel pump to another walbro 255 and checked yhe fuel lines plus I done a boost leak test , car boosts great and runs great but its lean , u can feel it . It needs a fuel pressure regulator , am running on 95 gas , should I try v power shell 99 octane?

99 will be safer for sure. The tune is for aussie 98 fuel. It is easy to rewrite the chip. Get it on dyno and ask for graph afr vs rpm and I'll write new one
Also, evoscan would be good too. Get fuel trims scaned as well.
