I did for about 3000 miles, I could smoke up a intersection with them and was running about 800 at 70, I sold mine cause I wanna get bigger ones

I have the stage 4'4 and without the box they perform very well. EGT's will get a little hotter, but not at all unmanageable. Smoke is minimal without the box on. Very impressed with the overall performance.

They are a pretty good bang for the buck, we have a truck running them making 545hp with a 62/71/14 Schied vp44 and Drag comp.

Jammer 5's are fine with the Adrenaline turned on or off in my truck. However, when I was running the stock HX35, they hazed good when you got on it if you don't have the wastegate adjusted to allow more boost. You can't adjust the wastegate higher till you get a box to boost fool the ecm. So yes, you can run Jammer 5's without tuning but they will be pretty smoky when you floor it cause you won't be able to add air to help clean up the smoke.

Ive had Jammer 5s for 20k mi or so and they have been great for the money, they are pretty smokey but its manageable, It also can ward off tailgaters if necessary. Currently Im running 60% WMO and believe me its smokey, but overall I think they have been good and easy to install, no pop testing here....and idle is smooooooth
