Exhaust Burble problem
I have a minor question but it is pretty strange which maybe could be a bigger underlying problem. The problem is that the car's exhaust burbling sound actually varies time to time. When I first got the car, it seems to burble a lot, now I feel like it's more softened. The car were all in working temperature and at same gear and rpms when comparing. The only difference is that I have installed the renntech valve control, and I don't believe that is the problem. Could what gas is used be a factor?
Thank you

The "Burbles" are timing adjustments (retardation) where a small amount of unused fuel escapes to the exhaust chamber and ignites. That sound/happening is reserved for S+ and R settings only.
