Ran my RhS headed 410 Friday....
Just looking at the raw numbers.
If you get it to 60 in the mid 1.4x range, it will knock roughly 3 tenths out of your ET. Low 1.40 gets you in the 10.70's is my guess. Figure 10.90 to start and find another .1 or so in tuning. Sounds pretty doable.
How did the converter react, you recall where it flashed, RPM in the traps?
Might have to slow the front end coming down.
Let me know when you hit Fontucky.
Where's the video... LOL
