As of right now, Crome has a 2 step, But there is a better one still in Beta form(cuts ignition instead of fuel), It works in conjunction with Cromes FTL/FTS plugin, In order to run the 2 step you need to get a Bin that the owner/maker John made, The only thing thats trying to be worked out right now is the fact that the script wont work with the Advanced Boost tools(20X24RES Maps, and a few other goodies) It only works with reg boost tools, and the fact that we are trying to add more fuel the the plugin, to make it work tits. Right now I am able to build about 8PSi off the line, but the car seems to run a little lean, Im sure within the next few weeks the working plugin will be up and working perfect.. Other than that you can get MSD's 2 step module, It will work. Just not sure what else you need to run that way..(coil/Ign box??)
