Car runs horrid...

[PropXprt]

Mods in profile are current... I did a boost leak test and do have a leak somewhere but, not so bad that it would make it run the way it does. I also did a compression test last night and got ~140 on all cylinders. Put new plugs in today as well, ngk's. The problem is as soon as I put the car under any load you can feel it start to lose power. Maybe you all can find something obvious about the log I have attached.

You need to tell us more info, what are your safc settings, how does the car run during this, any smoke or other problems? It's obvious your knock sensor is going crazy, because 30 counts of knock is not safe. Who tuned your car? Don't drive under boost anymore until you figure this out. Also how much boost you running? Just need more info thats all.

Pretty serious knock going one there.
Rather than logging fuel trim 02 log TPS so we know when your WOT.
I assume you have a DSMchip with 2x MAF logging included so we should double the reported Hz when we look at the log.

Ahh, figures I didn't log tps. I will most def do that tomorow and report back with results. As far as tuning I have the afc zeroed out, because the stage 3 chip was doing great when I had my smic on. Also I'm running about 14lbs of boost when I logged this, and the 2x maf thing is correct as well, sorry I didn't mention that. I sincerely appreciate the repsonses. Tomorow evening their will be another log on this post.

Alright I finally found a way to make this log legible on this forum. ~12-14 psi of boost this run.

I'm open for any and all suggestions.

Thanks,

Your still knocking badly. How old is the sensor?

 

[PropXprt]

I installed a new knock sensor two months ago when I rebuilt the engine. Do you think its worth a shot to install another one?... I probably have an old one laying around.
