I've had this strange knocking sound going on for the past few months and I'm not sure what it is. It does it while idling, while driving at a steady speed, while accelerating, but NOT while coasting. It doesn't sound like piston slap or bad bearings, at least not to me. 

 

Here's a video of the sound I'm talking about:

 

 

As you can hear my idle is still set too high

Probably not built quit as well as others.... just like the overpriced DDP injectors.

I'd go 50-75hp and roll on in your case!

I would do 100's as they leave you open for more in the future and you can just turn the box down.   There is no need to have the box cranked, but in the future if you do want to go with a he351 or a 62 type turbo you will have enough fuel.

There is a reason to have the box cranked when you have an edge....Gives the best fuel mileage.

That sucks

Eh, it is what it is. Shouldn't be as much of an issue with clean injectors :-) if I had know what I know now when I was looking for a tuner, I might have considered quad a little more. But I was concerned by what I had read about their past performance. Plus there is something to be said for the comp's reliability and simplicity. I need to do some testing with the comp on higher levels with the wire tap unplugged to see if that improves fuel economy.

Personally with +50HP injectors you fine with a stock turbo. Larger turbo is just going to increase turbo lag and smoke during launching.I think I remember @Wild and Free running +100 HP injectors with his HX35 turbo back in the day.

Wasn't me, never had an HX35, mine was an 02 auto so was an HY35 for me.  I went with 90HP BD injectors the same time I installed the BD Super B turbo, ran this for a short period and then made the jump to 155 hp BD injectors and the II silver 62 turbo.

Well it's been almost 4 months now and the truck is still running great! I've been so busy I never have gotten around to installing new gauges or tuning the pump
