Question Can stock injectors be damaged?

Can stock injectors be damaged by running them at to high of a duty cycle?

I didn't realize it was possible to run 14.5 psi, or even more than 9-10 psi with the stock 265cc injectors. Are you able to do this because of your water Methanol injection?

Yes the water methanol enables you to run 14 psi. The water cools combustion & methanol is extra fuel. My kit was $250 from a guy who never installed it on his car. New they are $245 to $360 from devils own.

I have been testing the limits lately around 16 psi & Im thinking I may have damaged the injectors running at to much duty cycle if that is possible. Im not sure yet may be something else but now all the sudden I get detonation where I did not get detonation before.

Also not sure if it has anything to do with it but I disconnected my midpipe just to see how it sounded. I drove it 10miles from my house & back. The frequency at which the downpipe resonated without the midpipe caused the catalatic converter ceramic material to vibrate apart inside. A few days later ,with the midpipe reconnected, I drove down a curvy road upshifting & downshifting reving the engine & must have caused the ceramic brick inside to slam around a lot & it caused it to completely disintegrate apart & shoot out the tail pipe. So now my catalatic converter has gutted itself. My car was really fast for about a week with the catalatic converter gutted but now im getting detonation. Not sure if it is because of gutted cat complications or injectors just gone bad.

Whenever I get $150 Im going to buy four 321cc injectors.
