tips and advice needed here please

if all goes well in the next few weeks a T34 will be landing on my doorstep to be fitted to my 2wd saph. it's already running a "stage 2" set up consisting of:

ahmed bayjoo 330 chip

RS500 intercooler

803's

3 bar map sensor

-31 actuator

"group a" cone filter

full mongoose stainless exhaust.

now basicly what i'm wondering is what am i going to be looking at adjusting or changing along with obviously the turbo? a guy on rsoc says i need a new chip, is that right even though it's the 330 chip? i'm guessing the fueling will need to be adjusted?

ok obviously i'm pissing in the wind a bit really because i've never done anything like this before so if anyone who has already done this could give me some pointers i'd be very very gratefull!

cheers
