Already tuned on stock dump, do I need a new tune for new dump?

Hey all, good to be back in a turbo again.

Picked up a FG MK1 XR6T ute with 330 - 400rwkw 98 to E85 flex tune in front of a standard ZF box with a true-trac rear end.

Current setup is F6 turbo with flapper and actuator mod, process west intercooler and piping, 1000cc injectors, fuel pump, & valve springs.

Has stock dump, cat pipe section is 3" with gutted cat and then into x-Force single 3.5" cat back system.

What I want to know is how will I go with bolting on either a 3.5" or 4" dump pipe?

Will that still cause boost spike issues?

And if no, at my power level is 3.5" dump and 3.5" cat delete pipe more than enough? (No further power increase planned)

Can grab some Forscan logs of MAP if that would help anyone in answering my question.

Righto...

 

So that's the bit I'm hoping to avoid. PCMtec tune is tuner locked and I live no where near where the original tuner (lessons have been learnt on staying close for after sales care)
