No regulated return.

Just out of curiosity what type of oil r you using currently.

I use the Valvoline Premium Blue 15-40. The one with the Cummins symbol on it.

Well it was worth a shot. Im runnin Rotella 5-40 Syn. Thought maybe that might have somethin to do with it but maybe not.

I'd like to bring this back up to see if anyone ever resolved this warm rough idle with the Adrenaline. I have had this same issue since installing the Adrenaline and have taken many steps in replacing parts to try to fix it all to no avail. I have had some improvement with recent tuning adjustments to my chip(non-PHP), but it is still present though minimized.

Anyone figured this out?:shrug:

I had the same problem after installing an Adrenaline a couple months ago - more "lope" at idle, mirrors shaking, could even feel it in the seat. Bob Riley recommended I talk to Bill at PHP and that discussion resulted in a 6 position Phoenix replacing my Banks chip. Now, at idle on the stock setting the engine is smooth as anything, and it only gets a little bit rougher (injector clatter) due to higher ICP on the non-stock settings but still not as bad as it was before the PHP.

Would you guys still recommend going with the adrenaline?

I am putting together a wish list for the missus...If I ask her for things for my B-day...and she doesn't get them, I get in less trouble when I go out and buy them for myself...

The Adrenaline is a great pump, IF you NEED a pump. I would not just go out and spend the money on it just to have it though, if my pump were good. My pump went out and the Adrenaline was not much more than a rebuilt factory one. It is a great upgrade when you need it.
