about mid december before the plog and i was getting about 7 to 8 degrees of nasty kr. I installed my SS plog about a week ago and scaned a few days after i was getting between 4 and 5 degrees of kr. It was about 30 degrees for both scans.

AFTER the PLOG you were getting 4-5 degrees of KR in 30-degree weather?

Move to a 3.5 pulley ASAP. You should get ZERO KR in this kind of weather. No exceptions.

i have a crappy intense tune, i just need a better tune and a 3' downpipe and that should kill the kr

alot of gtp guys are getting more knock in the winter, one reason mite be because of the crappy winter blend gas, here'* a link on the topic

and who know'* i mite be knock free in the summer with the same mods

Ditto! well, almost -I didn't have mine skewed. I do have to say with the P-log on the new motor for all of 2 weeks and then swapping to the stock mani I didn't notice any difference via seat of the pants or eyeing the stock guages.
After a bit of thinking how I melted my #3 piston and I feel it was:

1. P-log with no skewing

2. Ported SC outlet where the bar was removed between the boost release valve (if that'* what it'* called) and the LIM inlet wasn't opened to match, creating a turbulant flow into the cylinders, which would cause misfire -aka KR.

3. Combination of 1 and 2.

how hard is it to install Pacersetter headers, i'm thinking of getting a set, and selling my plog.

Y2k, you don't understand. If you're getting KR, lose the 3.4 pulley. You're causing damage right now. For the PCM to detect knock and retard the timing, the knock has ALREADY HAPPENED.

We had 3 popped pistons last year. You wanna start a new club for 2008? If you have KR, regardless of the cause, fix it, or change pulley sizes to kill it.

Then describe this 3-foot downpipe and 'crappy' INTENSE tune so we can help you further.

I'm gona get a set of pacersetters, i just wont go WOT untill I get them on, and if that dosen't kill the knock I'll move up a pulley size

First off, you shouldn't be running a 3.4 and 1.9RRs without headers, anyway. A PLog is nowhere NEAR keeping up with that.
Truth be told, with that setup, headers, downpipe, and a highflow cat are near-absolute necessities.

thats BS many run a 3.4, 1.9 rockers,PEMs, and run knock free. Every cars different, its obvious in my situation i need headers or IC to run knock free.
