98ron should be fine.. a Knocklink/Detalarm would be a good investment for piece of mind though.

cheap upgrade is the 4pots off the newer car.

as to tyre pressure.. start at 30psi and try up and down a bit until you find a nice setting.. usually around 33psi front and 31psi rear.. but personal preference comes into it.

Plug NGK PFR6B and set to 0.7mm

If you mod it then consider NGK PFR7B which is one colder.

If you can find no evidence of the coil packs being changed then you are likely to suffer a spark misfire when remapped and running more boost.

Engine oil - I like Motul 300v Competition 15W50
