Plenum spacer without map

[.:Bullen:.]

Hi all

 

I've got a plenum spacer that i bought from jez my question is it ok to fit without mapping it in?

 

It's currently a twin turbo setup mapped by jez but my rocker cover gaskets are leaking so seems perfect time to fit the plenum spacer as I have to remove it all anyways to do the gaskets.

 

Any help appreciated

Yes, it's fine. Just won't see much benefit til your remap.
