It is your choice when you do the install.
Figure first time install maybe 4 hours maximum
Better from costing if someone else is doing the SC and w/meth install plus once then to do custom tune for both.
What is important though is to custom tune to best that whatever mods you mix and match are considered in the tune so that all behave well.
w/meth is going to reduce intake air temp as much as 50 degrees so it is important for tuning so that PCM is adjusting to what might be blind temps of w/meth on meaning the IAT sensor maybe before the w/meth nozzle so it never sees the lower air temp
Never install nozzle so that is is spraying on MAF, we sell our kits with right angle nozzle so that spray is directed into throttlebody only.
I do is tap the intake manifold to mount nozzle after the TB
Install is fairly easy,
Pumps are pusher types thus the windshield washer tank if used or if using another tank must be higher then the input side of the tank.
Mount tank, you want the nozzle higher then everything else so that fluid drain back to tank or pump and not intake intake.
The further pump is from nozzle like it installing in trunk the harder the pump is to push fluid to engine, could then reduce pump pressure.
Make sure then pump is 250 PSI and not 150 PSI.
Install a fluid solenoid close to nozzle as this way when water/meth is off the engine cannot suck the fluid out of the tank.
Now all is needed is installing the controller and doing the wiring
I suggest you make a new voltage circuit in fuse panel and pump on cold start current draw can be over 10 amps just for the w/meth system.
Use like a "Add a circuit" found at auto parts stores.
I suggest you add a single pole power switch as there may be times while driving you want w/meth off.
Also nice is a LED mounted in drivers area attached to the wire from controller to pump.
The LED when on and pulsing lets you know the controller is commanding a PWM voltage to pump and that is is on.
