All these ECUs will do the Job just fine, Nistune is hard to go past with is control and price, Haltech is really something special but over kill, PFC is very good tho I find Djetro versions a pile of crap.
If your Racing Id go Haltech if its a wild streeeter Nistune, PFC are just are much more basic than Nistune but cost 4+ times the price.
