Here's a video of me running through 1st and 2nd gear short shifting at 6k rpm. I didn't want to go any higher until I get a tune and I know for sure it's making power up there. I was on a dirty gritty road so hardly no traction at first but normally those tires hook really good. This would be roughly a 1/8 mile run. I got out of it at the beginning of 3rd gear. Enjoy!
