MrFred said that the frequency can be changed with a patch and you've seemed to become well versed with the coding...think you can find a way to edit it?

I do not recommend this, tested it and it didnt seem to work well. They need to be as far in the runner as practical to work best it seems. It works great on ITBs in an NA situation but in boosted it seems to have distribution issues. T1 doesnt use the hat injection in his Kinsler anymore last I talked to him just the upper and lower rails mounts in the runner.

Aaron, I was more referring to something like two injectors stuck in the upper intercooler pipe.

I have no idea if it works or not, but it seems like it might work well with alcohol fuels, giving the fuel more time to evaporate and cool the charge before entering the cylinder. I could see gasoline having trouble though.
