He's saying he is on the factory tune. In the video he says the only "mods" were front/rear seat delete. He has another video where he ran 10.22 with only a drag radial. Those were done at Atco. From my understanding that's a quick track. Lots of people getting personal bests from there.
I am the guy who recorded the videos and posted them to my youtube channel.
The 10.22 was done by a guy named Chris...His car is a narrow body and it is 100% stock except for a drag radial...He had no skinnies and full weight...In the description of that video I put a link to a video proving that his car was stock after that pass.
The burgundy Redeye that did 10.15 was a guy Joe in a wide body redeye that was all stock except for drag radial along with removing the passenger and rear seats saving 120lbs.
I also witnessed Joe run 10.14...Since then Joe has gone a best of 10.10...When he gets skinnies I say 10.0 maybe 9.98.
Sean just did 10.27...I saw Sean go a few 10.4's and posted 1 of his runs on my channel..I also saw him go 10.3 all stock with just a drag radial.
These cars are consistent 10.3 to 10.2 all day long with just a drag radial.
I plan on hitting 10.1 with my Redeye on a drag radial and skinnies...I am keeping my car 100% stock other than tires.
