We have been told since update 1.0.0.3 that there was something up with the turbos blow off sounds. But we only develop mods oriented towards multiplayer sessions. We have hundreds of hours of video for we run a YT channel and stream M-F normally 9am till 2pm est. We have never had this problem with the blow off value noise. We think there has been about 5 to 10 people that have had this problem. Most though got our mod from some other site where we don't upload to. We still got plans on going back and fixing a few more things. We are hoping that v 1.0.1.5 will be the last update we will have to release. We still want to get the truck bed to hold crop/dirt. We haven't disappeared we just took a hiatus from it for it was starting to consume every bit of free time we had to work on it. We are truly a super small team of two. I am mainly the one who codes and builds our mods while the other team member test them for errors. We are truly sorry you are having the blow off noise issue. For on our end we don't think we hear it enough. Its coded to only go off when the engine hits 100% engine load. Which on our end for our normal use of the truck we hear the blow off noise every few shifts. We originally wanted to make the sound happen every time you Let off the accelerator pedal but it wouldn't code right for that to happen. For in most cases things with turbos at least anything I ever owned in RL that had a turbo you would hear the blow off go off every time you let off the accelerator pedal If the turbo built boost. Thanks for the input and we are truly glad you are enjoying our mod. Stay on the look out for hopefully the final update v1.0.1.5. Released date to be determined. Thanks again.
