hi, what sort of gains would i get using a water/meth kit with the stock ko3s? the car is currently making 218bhp and 270ft lbs, im mapped on a revo stage 2 but seeing what sort of gains people have had with these with a custom map or setup with an sps controller allowing for more timing with data logging etc. i realise they allow for more advanced timing but wondered whether its worth it for the money or just go for a hybrid ko3s which is a guaranteed 260bhp or potentially more. what are your views or anyone who have used this with the stock turbo with a similar setup to me. Many thanks
