Ok guys, I know the tune and supporting upgrades should change the sound some. Hopefully a faster idle. But this is what a sinister cam sounds like with summit 3" ,x pipe and turbo mufflers. You need more than a phone to really get a feel for the sound. Anyhow it's tuned for the mild cam now which is probably why it's running as well as it does. Let me know what you think! https://youtu.be/mHo6-gi1yAM

 

A tune is not going to change the sound much, especially at anything more than idle.

Higher RPM idle will smooth it out a bit, but that kinda cam is going to lope hard no matter what you do to the tune.

 

Yea I like the sound I just want a little faster more aggressive lope. It's at 700rpm idle now gonna bump it up to about 900
