Well unsure of the cause of it. I did get a catch can. It’s upr dual valve catch can for procharged mustangs only. But before I installed the catch can this issue had already came up. Hopefully it isn’t anything major

Thanks for your input. I’ll get started with a compression test on my day off and see where this stands. Any certain number or difference in cylinders these cars should be reading?

Hey guys my car started to blow white smoke out of the pvc and driver side valve opening. It used to do it before but very minimal. Now it starting to really blow a lot that it comes out of the engine and is noticeable. Doesn’t seem too good but car runs fine doesn’t seem like it has a major...

Appearantly so. Car feels different. Feels good. Idles a whole lot better also that’s for sure. Don’t get me wrong I still get knock but very minimal 2-3Kr as cruise only quick blimps other than that at WOT, NOTHING.

Just wanted to give a quick update on this thread. My tuner dialed my car in! Car still does read knock. But very minimal compared to before And only on cruising minimal knock reading. WOT AND SHIFTING NO KNOCK RETARD WHATSOEVER. Car is a whole new animal now! No more issue with that I’m free of it!

My car is currrently being tuned by Alothman. He’ll be turning up the power more on my car when I get some cold weather here in California is hitting 115degrees Fahrenheit. But definitely keep you updated. And my issue did start from the begging of starting with Lund Racing. From beginning to...

So I ditched my tuner where I was getting crazy knock. Went with a new tuner. Did not tell him about my issue. Knock is only present now on shifts to this point. And knock at the max reaches 3.50 compared to the old crazy 10.+ with my old tuner. Thought I’d share my point on the tunes. I am...

Sorry for being annoying man but any updates? Did you solve the issue?

So do I! I have the same issue as you do! Lund ran out of ideas they’re not sure what it is. They don’t want to deal with the knock sensor. Please let me know as you test or fix! Trying to figure out if mine is the same issue since it has the same identical problems thank you!

Do you also get some knock retard when you shift at wot?

I’ll have to run my exhaust and check for some leaks. I have the procharger p1sc1 stage 2. And have it set with the belt that came with the kit and tightened to instruction manual.

I’m not sure exactly what it is but I also have this issue. And I also have a procharger mine is the p1sc1 stage 2. Kman11 if you do switch out your clutch and drive shaft, please keep us updated. Seems like we are a handful with this issue.

Were you able to fix it? I have the same problems. I have a 2012 mustang 5.0 p1sc1 procharger stage 2. Get the same reading as described. Big headache. Been going with it with Lund also and can’t seem to find the problem. I posted on Facebook a while ago about it. Someone said it can be my...
