Simple question, Simple answer and why
Thanks

 

This question is really vague!

What car, what type of motor build? full standalone or piggy back type?

 

It depends, for many reasons.

 

Lol, but in all seriousness, I really like my PowerFC and would recommend it to anyone

 

It's not a simple question or simple answer. Do you intend to do the tuning? Are you experienced? Consider the knowledge base for the particular system on your car.
If you will have a trusted shop do the tuning, IMO you should go with what they're most familiar with.
