One injector louder than the others?

[2000_f350]

I have an early 99 with a ts 6 way chip. I drive it on the +50 tune and when I lay into it a litle I sware I hear one injector over the others. Or am I hearing something I shouldn't be?

On the 7.3's the number eight injector which is the drivers side at the firewall is always louder than the rest.This is known as injector cackle and there was a tsb back in the day how to fix it but it never really worked.There are some new fixes out there now if you search around.Hope this helps.

I thought on the early 99 all injectors were the same.

Thats what the tsb was for.They were the same and wanted you to change number 8 with a different one and some additive.Supposed to fix it.
