I recently did calc.vet with the help of weathermanshawn and Joecar, it really helped the truck out. I notice the truck still feels stronger when it's cold as to after it's warmed up. I mean if I barely tap tge gas it will spin. Once it's warmed up I really have to try to get it to. The truck just feels stronger period when it's cold. Why is this? And is there a way to make it that strong the whole time?
