At this level just plug in.
Would be wise to have a full load fuelling check on the dyno as it might save the engine if there is anything amiss.
If it is all ok then the chip at this level will be perfectly ok, and NOT likely to benefit much from LIVE MAPPING.
I would take it to R/R to have boost set at the same time, just for peace of mind.
I recommend MSD for a chip, but some like others like NMS.
