.400 pro tree help

been working with my 7.0 Index car
And seem to be having trouble with cutting a good light and looking for a little insight
Actually made it past the first round last Saturday
And then broke out
At this point I’m leaving at 3200 rpm
With a 1.44 60 foot
And ran a 6.91 just didn’t lift soon enough
But my lights are .152 ish
Which just will not be competitive
Once a few rounds in
I’m using a pro brake Transbrake
I’m thinking maybe tasing the two-step will help
Anyway just looking for some suggestions from the bracket racers
