Yeah I'm gonna have a separate tank in the back.
There is the base kit which uses a adjustable 6-30 psi boost switch so you can adjust when it starts to inject meth.
And the expensive kits use a progressive controller with your map sensor to adjust how much meth is injected as your boost increases etc
BUT although the controllers are good, apparently with all the companies the controllers are known to either fail or just be a general nightmare. So for simplicity and reliability your better with just getting a devils own base kit
