New HPOP: Clicking noise only under load and high RPMs

Hi all,

Since the weather has warmed up my truck is starting and running a good bit better. I ordered a TE500, stage 1 rosewoods, a 6pos TW chip, and some gauges.

I decided to install the parts individually (at least where possible), to make sure that each piece is good as I put it in instead of having all parts to troubleshoot. Last night I installed the TE500 (replacing a 15* that could maintain approximately 2400psi) and took it for a test run (no computer). I noticed a new ticking/clicking noise that seems to be coming from the engine bay, but only under heavy throttle and when pushing the truck (neutral/clutch doesn't do it). It only occurs at and above about 2700rpm. It sounds like 2-3 clicks per second. It isn't extremely loud, but it is definitely noticeable. I checked my oil level, and it was a bit low, so I filled it up which quieted the noise somewhat but its still there. I have never heard this noise before. Any idea(s) on what might be causing it? Truck still has the old worn injectors and no chip installed. Would extra oil pressure at high RPMs make a failing injector significantly louder?

I have not yet hooked AE up to see what kind of pressure levels the TE500 is maintaining.

Replacing parts with upgraded ones can make these trucks start doing mysterious things. I would have to say it's an injector. But try narrowing it down if you can. Maybe a buzz test will tell you if one is going lazy on ya, at least you got new injectors waiting to go in.
