Self fitting throttle bodies

[MTW]

The next big thing on my list is individual throttle bodies, but I am keen to do as much work on the car myself.

from looking into it the options seem to be take it to somewhere like team Leo's for jenvey's and a custom map, or buy the Caterham roller barrels at a slightly higher cost. 
 

am I right in thinking the Caterham kit comes with everything you need including a base map, so in theory would be better suited to fitting yourself? Or is it easy enough to figure out everything you need to fit the jenveys?
 

Keen to hear from anyone who has fitted individual throttle bodies at home.

I didn't fit my RBTBs but Luke Stevens fitted Titan branded bodies with all the other stuff needed, including a full custom remap and carbon trumpets for less than CC wanted for the Caterham branded kit at the time, not fitted.

They are straightforward enough to fit but depends on how mechanically minded you are and they will require a bit of set up and then the fuel and spark calibration done
