Should I get a tune for a catless exhaust system?

[Astroboy]

I am running an ago turbo kit stage one with the base map. I have an all catless exhaust and was wondering if a tune was needed.....

I am no FI expert but from what I have read and seen, you should only rely on the base tune to get you to a tuning shop, where you have someone do a custom tune. Correct me if im wrong FI folks.

A full catless exhaust was probably not used during the base tune so you would want to tune it anyways.

Base maps are generally safe maps to run, so you might not blow anything up, but there's a decent amount of power to be gained by getting a custom tune tailored to your car. Unless of course it's a crappy base map

I have been on the AVO base tune, stage 1 kit with BOV and an Invidia catless resonated front pipe. The concept of a base tune with sufficient R&D equates to the "stock" tune. This should be able to tolerate a little change like going catless.
