Jakeman68 you are doing the community a huge service with your inside info and we appreciate that.
However, im just not convinced the problem these guys are having is because of grand intercooler efficiency...... what a crock.
ICs have been front mounted for decades and there has never been these issues. I think the "shudder, studder" problem is more fuel or spark related but i dont experience it at all so thats only an opinion.
Replacing the cat is a start but remember there is reason they are going bad... OVER fueling!!
Either way thanks for keeping everyone informed.
