Wez, am sure a boost gauge will be required for mapping.
Unless Jon has one he uses for setups.
Best to get one though so you can tell what is going on with the car.
And as for Knocklink big yes most people say this is the first thing you should do on an import before mods, so with what you have its a must.
Jon will prob have det cans for the map, but is a safety for you afterwards, lets you know any sign's of trouble.
