No clue on that but I scrubbed 10+ mph and lost a chunk of et but don`t remember exactly how much. Plus as I told Mikey and was correct in that the dyno tune would be off and it is. Jason had the mixture screws 3/4 out and it ran bad till he brought em out to 1 1/2 where I had em and it wants more jet as expected also. Dynos are a tool and a way to see if our junk leaks and set BASIC starting points that`s it imo...........That car will go easy 9.60`s or better.............
