I know there is multiple threads on this but I was just curious, I know getting an Intercooler could add around 10 hp but I haven't really seen to much on the type of HP gains that are possible with meth/water Injection, im assuming it also depends on how well the car is tuned for it ( I know its not a set number but maybe a percentage?) . I want to know what would be better for longevity/ hp gains/ price. The car is my DD very minimal mods, intake, catless dp, hopefully more to come.
Thanks
