While the Jars are indeed louder what is key in the complete system is the header which provides much better airfow into a larger collector and therefore matches up better with the tripe KN input filters. That is the specific configuration Wayne developed that tune for. I have spoken with Wayne many times and believe there is 15-20 HP in the header alone with that tune. BTW...The jars without baffles are Subwoofer low and loud! My opinion for what its worth is that 20355 would be to rich without doing the KN 2780 filters...All the Best..JAG

Well I did enjoy the ride today with the 20355 tune, the motor was the best it's been. Very little diecel popping, improved performance.
Have not k checked the fuel consumption yet.
The next step is I will try the 20355-2, which has the ign tables changed and thhe seconderies 100% opened.

Well I down loaded the tune 20355-2, there was no doubt about the improvement in the first three gears but the decal piping was quite bad. Unless I was dreaming but the exhaust seemed a bit louder, anyway I went and ran the 20355 back in to get rid of the decal popping.
I think the next step is the PCV and a good dyno tune.
