I wouldn't remove the HFC's. I'm positive that we will have a tune for the HFC's so I would just leave them on.
EGT gauges are very helpful. The only reason I did not mention an EGT in my list is because a lot of people won't want to load up their cars with gauges.
When we build our 370 in to a race car we will have boost, a/f, oil temp, fuel pressure, EGT left and EGT right, and a couple more. But, for the average owner, this will be overkill and unnecessary to have this many guages.
Every now and then, depending on what the customer wants we setup a pretty trick EGT setup where the customer can toggle between left and right bank EGT gauges on one gauge. It's obviously easier than having two gauges but it's not practical for racing. For racing it's best to just have two gauges.
Here is a very good tech. article on the different reasons for EGT and a/f gauges.
