I just installed a h and s xrt pro, egr delete, intake, and cat dpf delete pipe and loaded the tune up and now it screeches loud as heck and I have no idea what's going on. The vgt gear arm moves like normal. Any ideas?
Dang you guys are good thanks for the help!
Did you use shorter bolts for the exhaust manifold? If you forget to install new bolts or completely leave out the bolts that mounted the horizontal cooler to the bracket, then the noise your hearing is coming from a leaking exhaust manifold.
Check the manifolds. They come loose. Seems to be the drivers side most often for me
