Just modified my exhaust by putting a lenth of pipe in the box, so now thereís no cat and kind of a silencer bypass.
Now the turbo really whistles and there was a bit of a squeal when I changed gear. The turbo now seems to spool up as soon as I touch the accelerator. I do need to check for leaks but could this be overboost? Anyone with a straight through pipe have anything like this?
Any help much appreciated, as is any help with adjusting the turbo if thatís the cause?
Thanks truck folk 👍🏻
