Mate seriosuly do listen to Stu, he knows a thing or two.
My old spec was:

701 injectors
4x4 Cossie intercooler
4x4 (.48) Cossie turbo
Filter/exhaust.

The chip was a custom one from MSD that he supplied for this kind of spec. It held 16psi and ran like a dream and was quick. Power was probably pushing 200ish?

As stated 195chip wil be for a T2 thats designed to boost up early and run out of puff late, which is NOT ideal for a T3.

Realistically imo you'd need a little more to get 200bhp but its been known before.
