Flow detect systems still available ?

[tweeqd]

I know ill be shot down and told to upgrade but i have a 1s system
Im running a t34 turbo on a 1.6 16v citroen engine, its making 360b@22 psi and obviously made no more power with the water/meth turned on due to not having the timeing adjusted
My mapper was reluctant to adv the timing as there is no failsafe on the 1s syetm

Is there any warning systems stil available for the 1s
