+1 to mddc but in addition I would say do be a bit careful about overloading your upper body, a useful test is to see if at time trial level efforts, if you can lift your hand or elbows off the bars for a 1/2 second or so- if you tip forward hard and fast then you may be overloading your upper body and the consequently may go slower, by means of increasing the metabolic cost of breathing and/or using breathing muscles for postural support.
If you tip fast, then possibly nudge your saddle back 5mm and see if that helps.
