Sometimes when I let off the accelerator in my truck kinda quick I hear a chatter noise kinda like at the truck pull when they end there run. I had somebody else in the truck and they heard it and told me that my turbo was spinning backwards and that it is really hard on turbos. They told me my waste gate wasn't opening quickly enough. The higher the level of the programmer is the more frequent it happens. Do I need to fix the factory one or buy a new one like the one from Banks.

That.....is.....funny. Well even with your detailed explanation, I cant really say if you're hearing a boost leak or simply the normal turbo spool but I have to say that the "pop" is not normal. Since you dont have any gauges you cant tell what your boost and EGT's are so you have nothing to compare to. But you should still check your intake rubber boots for tightness and making sure they're in place because what can happen is they come loose over time and then boost will push on just off the edge and cause a leak. Of course that will only happen when boost is at its highest so maybe that may have been the pop you heard. A boost leak may not sound like a big deal but when you have a significant boost leak, your EGT's will skyrocket and thats bad. Depending on the size of the boost leak, you may notice more than normal black smoke coming from your exhaust too.

I had my intake elbow off several months back for something, dont remember what. When I put everything back together and went for a test drive I hammerd it and it took off then POP and I lost power. I had forgattten to tighten one of the clamps and the pressur partially blew on off the boots off. It did not cme off completly and I had to hunt for it. It s possible you ruptured one and that was the pop. You could take them all off and examine them or better yet pressurize the system with air and look for a leak.I am still working on the pen trick. Thats one we never tried as kids.

That sounds like a boost leak to me. On the big trucks I have heard a boost leak sound like a siren on a cop car! Anyhow, look closely at the boots for any movement and also check the boot at the inlet of the intercooler by the right inner fender. There have been quite a few that have had the boot rub and wear a hole that would only touch when the boot expanded and looked just fine otherwise.

I get funny looks with my 400+ rwhp and 30-32 psi and great EGT's :-)

I'll deduct that your drive pressures are in check by your egts. That's what tuning is all about. I'm running a TST comp, jl 8 x.010s and a smarty on my 2002, and have very little smoke.

Drive pressure, what drive pressure :-)I can tow at 0.8:1 or better. It only goes over 1:1 WOT above 2500 rpms.

Check your manifold bolts I've had one come loose and pop out hit the hood and fall back into the injection lines. That little hole is enough of a leak to drop you from typical max pressure down to 8-10 PSI and very smokey.

Cummin Dodge, did not mean to hijack your thread.thank you all for your input. Noise is coming from where the aftercooler is.
