Should I retune my ECU?

I have tuned my ECU, after I installed CBE.
Later, I did another mod ; Stillen G3 and HFC.
Because I tunned my ECU, before installing CAI and HFC,
Should I retune my ECU?
Someone said that it is not necessary.

Yes you should tune....Whenever adding a new part there will be effects....A tune is sure to put out the most potential HP that the part has to offer....It won't hurt.

You don't need to tune for a cbe. But you do need a tune after cai and hfc. Your car may be running lean now. Get a tune so you're not running too lean and get more HP.
