Hey there, just finished installing my Supercharger yesterday. However, I'm running an untensioned belt because I don't have a belt tension gauge. First, what are the side effects of running an untensioned belt? I ran about 20 miles with the Supercharger and I noticed my truck was surging like the belt wasn't catching. I'm hoping having my belt properly tensioned will fix this problem. Also, because I have that TRD Auto Tensioner device, does this mean I will only have to tension the first belt once? Will I still have to retension every time I get a new belt? Thanks a lot for your replies, your help is greatly appreciated!
