Is a new tune required for PR coils?

[Reaper0995]

FBO with mild tune currently, going to GC lites soon (on order). I have the PR coils and wanted to install them with some other parts while waiting on turbos to arrive. Will this be acceptable to leave the current tune? I don't want to retune it just for a week or two only to tune it all over again with new turbos.

Just click the checkbox in MHD. There's a revised dwell map with significantly increased values that will be out with the next MHD release but no need for anything custom.
