Im trying to plan out my RB swap the best i can. Im still in debate on a RB25 and RB26, but thats not the reason im here.

Please, im not asking how to swap and dont need any criticism on how expensive or better a 25 is to a 26 or 26 to 25
.

Now i have an AEM FIC-6 from my previous built and was wondering if i should incorporate that into my new build.

I know most factory turbocharged cars try and limit boost but im not sure about the RB ECU's.

So when i decide to go bigger turbo for more power will the factory ECU allow that or do i need some sort of piggyback to make the ECU happy?

Also. What do you think of a RB powered with a Borg Warner S252 with a Batmowheel and .55 A/R turbine housing. Thing spools like a beast. Wondering if i should swap to a larger Turbine housing though.
