Everyone with PPEs seem to be getting great numbers except for me. Only difference between other people's great results and mine is that I have aftermarket Camshafts. I guess my cams did not like too much flow, I went from 322whp with stillens to 309whp with PPEs.

But...Weren't you like the only guy with an HR that bought the stepped headers? At the time we all had to make a decision, there wasn't any data out there for HRs, so we all chose non-stepped based off of the results that those DE dudes (Denchan and soembody else) were getting.
I got non-stepped and was kind of kicking myself when PPE later came out and said stepped would be better for HR, but....we had early models, so who knows. I haven't installed mine yet (lol). Debating going the Z1 route myself, but for a different reason -- they've started doing visual inspections in Atlanta. I didn't find that out until recently...hence the reason the PPEs are still in the garage.
The shop I was going to take the Z to has no time obviously for me and my Z. I wish there was another place to do this unfortunately San Antonio is the closest place to me.
Well guys my HR going into the shop to install the Z1 headers and Z1 test pipes, plus bored out throttle bodies, NST pulleys and a retune. Lets hope for better numbers.

All hr headers are stepped unless specified. Those collectectors look the same as ppe`s honestly. Maybe your cam config and ppe`s just didn't get along.
my headers and test pipes get here on Tuesday!!!
let's hope for greater numbers!!!
