904 Flares on 2-3 shift?

@CudaFactHackJob got the car out this morning warmed everything up real good than launched from a 5300rpm hit no flare 1-2 2-3 . Pretty stoked as it was only a little low on the fluid which was causing the 2-3 flare. Topped up 1/2 litre problem fixed . Thanks on the advise
