Do the 450's tick abnormally loud. After my turbo install I'm hearing a loud ticking sound when on the gas or under boost. The reason I think it might be the injectors and not the valves is because they never ticked that loud before and when I rev it at a stand still the valves are a little noisier.Just not as loud or the same sounding tick when under load. Any input would be great to narrow it down.

put your 240s back in and see

my 450s dont tick a lot louder than i remember the 240s doing

Every DSM injector I have ever used was pretty ------- loud. I always just assumed it was because it was a larger injector.

mine are pretty damn loud, at first I thought it was my valves and wasted time realizing they were all in spec. Then found out it was the injectors.

Thats what I thought cause it didn't sound like every day vavle noise. Probably gonna do a valve adjustment anyways just in case. Is it louder for you guys when your on the pedal or is just loud all the time?

I never really noticed that much of a tick running dsm injectors on a dsm.

dam, so that's what it is. since i put boost on my car i've heard a tick. didn't sound like valves and my cars' valves wheren't sounding before. whata relief.

*my hypothesis*

They tick louder because we are shortening the pulsewidth to lean them out. I doub't they tick really loud in stock dsms but they tick loud as ---- in my car.

Um , did you check for an exhaust leak? Thats what my tick was.
