I posted a thread about it recently mate, Im fitting it friday to my esco, fairly simple and straightforward and on talking to a few owners of evo;s etc they tell me it makes a huge difference to charge temp, helps stop det, very worthwhile, and obviosuly more bhp.

the stage 1s kit is the same i have and it cant be mapped in, it just runs off the boost pressure switch supplied.

Use a old windscreen washer bottle mate and mount it in the inner wing
