anyone reckonmend the best way to go about this?

am building up a car at the mo, to which i am fitting a 1.8zvh turbo, spec is:

1.8zetec bottom end with skimmed standard pistons (am told its safe at 12psi boost)
cvh efi turbo head, recently fitted with a new piper cam (by SCC) but head standard other than this
standard t3 turbo
ofab management

havnt got the intercooler yet, will be a front mount or pace type, depends what comes up!

as you can see, not exactly a mad spec, just want reasonable power and drivability at this stage, with a view to upgrading in the future. So what are the best options chip and setup wise, I am in welwyn garden city in herts, so close to SCC who have done a topo job setting up cars for me before. Will a standard chip then a setup be any good (ie a 165 or 195 chip) or do i need a custom map?

thanks in advance
