I have a quick question on water/meth injection setups. Are they safe for widebands? Also, My current afr under boost is in the low 11s. I was wondering if this will change by adding water/meth injection or should I change the AFR to something else. I dont know if it matters, my bike is an 02 gsxr 1k. I am asking here as there are more turbo experts here than I have seen elsewhere. I do have a Busa but it is not boosted. Last question, will the water/meth injection fool the PCV autotune in any way?
