I think you are driving the wrong cars man
All my injected cars have been much more responsive than carby and yes you can easily give injected cars a big pump shot of juice if that's how you like it. These days they tend to tame them down a bit so you don't have too much grunt (Holden have been worried about this ever since the great plauge of looped around granny driven VN's in 1988 :p). My mum actually test drove a 1988 VN when I was a kid just when they were first released, she refused to buy it because it was "scary" compared to her VH
she was ready to buy too, but nope, couldn't handle it
