What are they trapping in the 1/4?

Check this out

11.3@121 for JB4

11.7@ 119 for BMS Stage 1

11.7 @ 119 for Dinan

Not sure how accurate these are but makes sense as M550i with a real flash tune plus downpipes can run high 10s/low 11s at around 125/126. I think this puts just a good ol flash tune to around the 11.3 mark at around a 123 trap.
We have a forum member with a M550 that's running a flash tune and downpipes who's hitting 1/4 mile in 10.82s @ 129.65 MPH
