Weird issue?
I recently replaced my FICM, #8 injector and updated to the newest flash on my 05. After that I noticed that the truck's exhaust sounded differentley at times at idle. I have a 4in straight pipe and I can notice any sudden changes with it. I don't know if it's part of the new flash or what, but what it's doing is loosing it's 1psi of boost at idle. Enough to make a significant noise difference on the truck. Is there anything to worry about or to look for? Thank you.
