MY dyno and ET slip, What do they tell you?

Without knowing much more.. Is the convertor a 10"? Are you leaving on the convertor or off idle? What tires? IMO, if you are looking for ET and not concerning with drivability... You need to work hard on that 60'. Tune the shocks, and work on the launch rpm.

Edit - I didn't read this answer.. This looks like a chassis dyno record with an O2 trace. Is it a chassis dyno or engine dyno? If it's engine dyno, what were the BSFCs over the power curve RPM?
