ZZP Powerlogs
Who'* used them with good results? I'm thinking about some exhaust mods and wanted to know if I should consider these.
Lets hear your stories

I spent the last month reading, asking, researching these things and in the end I've decided to get headers (in the spring) over the PLOG.
Isn't worth it when you need to skew the front injectors by 2% and headers outflow by a huge margin for a few hundred more.

Unless, of course, you have an SE, are NA, and no plans to go major cam or anything, then it gets harder to see the advantage of the headers.
I now know personally, three people who are running P-logs without skewing and like the results they've gotten. Since I don't have them myself and have no numbers, it means little for this thread, but I felt it still worth mentioning

Being N/A, I've researched the PLOG, too, and here'* what I've come up with:
1) The mild steel version often develops cracks at the primary-to-log joints within weeks.
2) The stainless version is mated to a mild steel head flange and crossover flange recycled from a stock manifold, and often cracks in those spots within months.
3) The ceramic-coated versions often peel within weeks to months, putting you into case 1) or 2) above.
4) No one has ever proven a PLOG to be significantly superior to a PEM (to my satisfaction, anyway).
If they ever came out with an entirely stainless version, it might be worth looking into, but would likely be cost-prohibitive.

I have never dynoed my car without and with the PLOG..
But being that I was in a Crunch, and on my 2nd motor.. I told them to toss the ported Rear Mani and Front Plog in the trunk...
I have driven the car 3000 miles on this motor on a Stock manifold set up and am finding I was happy with the PLOG and Ported Rear... I did not crack the PLOG but didn't have it long enough for a real world test... And once the Skewed injectors were in the Car ran better... I am wanting to install them back on the motor, but some physical issues have halted that so they will Wait...
Lash and Sandrock both drove the car with and without the PLOG/Rear Ported... Both will tell you it was an improvement over the Ported Front mani...
But again I have no numbers to back that up
