I havent checked on prices lately but looking at the first question, the BeeRev isnt near in comparison to the AEM standalone. When I adjust my 2 step I can choose timing retard, rpm limit, also whether I want the limiter to go off of fuel cut or ignition cut. Ignition cut creates a lot of back pressure in the exhaust which in return creates a lot of boost off the line. The aem and haltech after AEM's last update is very similar in comparison. AEM now features flex fuel, 3 step (No Lift Shift) and several other features. One standalone that has been coming on strong in the supra world is the ProEFI which I am sure Z's are running them. Although there is a line where I consider it as wasting money and buying optimal equipment for what I am using it for.
