If you’re not changing anything when swapping from can to pipe, then it’s really hard to judge
How many turns are you running on the T handle needle for Can?
How many turns on the T handle for the Pipe?
You should have a noticeable amount of difference in performance, so much that if you had 2 karts identically set up, same kind of driver, the one withe the can would have a hard time catching up to the guy with the pipe. FastFreddy.
