Hello, so I currently have the Hiss tune. Very little rumble(randomly)usually when the truck is doing a VGT sweep. Anyways I was just told rumble is not available for LML?! I got the hiss sound. Only have rumble for a second or 2 (randomly) And I was asking my mechanic. He said they told him they won't do the rumble tune bc it changes the VGT and will cause you severe hesitation/dead spot at idle?!? SMH...…………………………… Like how bad have you guys notice this type of situation? Like am I just going to be replacing the VGT sensor constantly(how many miles/times until???) Im so confused why? Is their not a way to bypass this headache?

Thanks again!
