often what is called "stage 3" cams give a wild and irrractic idle due to the loss of constant manafold vacuum at idle. Often the ECCx cant control this and a patch up chip to control the idle is neaded. Throught the rest of the rev range the EECx should handel it.
Headwork and a new cam often help the I6's fuel metering as it runs very rich (10.5-11:1 at WOT) on a chassis dyno, and being a MAP system the engine management doesnt know more air is going into the engine and will keep the fuel maps similar to stock, hence bringing the AFR up to a mre appropriate 12.5-13:1.

You need an EL computer, if he's too stupid to write on them as they come out of the car you don't want to deal with him anyway.
If you're getting an aftermarket computer, consider the MAF sensor conversion, I believe Rollin has done it on his? Well worth it if you're going to go to that sort of cam IMO
