With the JB4 he ran 114mph but was traction limited with only a 2.4 60' time. I think I read he made 390rw with that combo and I'm sure it could run similar times with traction and maybe a setting change or two. On the other hand his results with this Cobb combo were great too. On the JB4 end I know they have stronger maps and settings being tested now and when those are released hopefully we'll see another dyno comparison between them. I suspect they will be pretty similar.
