i was just curious about that s472 kit you had i kinda want to do a single instead of twins almost never tow. did you like that set up for daily driving and weekend thrashing? just wondering your opinion on that set up pro and cons thanks!
What u are hearing is the veins cycle in ur stock charger. Totally normal sound on any Dmax made after 04.5. U can tune that out with efilive as I have done to many, and many on the forums have also. Thanks.
Hello, I have a 07.5 duramax with an afe 4" straight pipe, afe cold air intake, & black max tuner. When it idles it goes from a nice low rumble to a loud hiss then back again. What is causing this & how can I stop it?
