each one of the MC1 outputs can be used by itself. So you can use one to control a boost solenoid and another to control the meth solenoid. We (Torqbyte/Us) just released the new updated controller, with more outputs and inputs and faster speeds and etc. I need to update my site.
Nozzle size, if youre doing chargepipe, you will probably need bigger than 375. 225ml DP meth weve made 600-700whp. I don't offer an SS/AN line combo from pump to engine bay as most peoples its pumps use pushlock.
Stock, im doing an inventory, because i ran out of a lot of stuff fullfilling 100+ orders when i came back from being gone for 3+weeks. So i would wait and get it sent to your new address.
some of your questions i think i answered in the actual FG1 thread. As stated in the FG1 thread and website product description, you can not use the FG1 and FF at the same time on the DME as they share the same inputs.
