i ground my stock plate to match a "0" plate exactly,,, i held a "0" plate next to it and matched it almost perfectly. .
i was pumped about putting it in vs. the #5 all the way forward and when i went for a test drive with the new "0" slid all the way forward,, not only did i not have as much smoke, it didn't seem any faster at all /if there was any change/ it was a little slower!!
so after the test drive i parked it and put the #5 back in.
