New injectors came with a clacking noise

[chongzilla]

I put a set of 8 AD code injectors in my e99 f350 yesterday. #8 cylinder got the AE code injector. The truck starts and runs out well but I hear a loud clack coming from a cylinder when pulling out of a stop or a low rpms on the highway. Its gone when I have my foot on the go pedal and the turbo is spoiling or when I'm pulling a hill. I've only put around 150 miles on the new injectors. It's loud enough to cause concern so here is my question. Since I replaced AB code injectors do I need my ECM reflashed to a later model spec or is this some other issue. I was wondering if a fueling issue could do this since the clack is gone when I'm under acceleration or load while doing highway speeds.

Nah you shouldnt need any tuning but custom would help.

Mine has done that since the ae went bad at 2 years old from new. They put an ae in. It made more.noise. They put an ad in. Good to go.
