Having Johan look at a log and he says I'm getting lot of knock readings. I'm hearing a little more exhaust rattle noise too. Power seems to get stuck around 4500 rpms.
We were checking the normal questions, good gas, yes 93 and same station as always. Then he asked about metal sounds.
I have a no weeds electric exhaust cutout system on and believed that the clamps weren't tight enough. I have got some small rattle since installed and been meaning to recheck all clamps or just have them finally welded but haven't yet. I guess the overall noise is a little more over the last week or so while I've had this 4200-5000 lack of power spot (it's like a complete lack of power, lower than stock 5.7 hemi acceleration)
I'm going to check obviously but for my knowledge I'm wondering what the range of things I should be thinking about. Can't get to car and under for a few days and am curious/anxious.
Cats going bad? I literally can't think of anything else. No cels
5.7 procharged johan tune, 3.4 pulley, 7psi around 5k, dayco tensioner, stock exhaust manifolds + no weeds, 3200-3600 stall, tranzformer
