Bigger chainring?

Hey folks,

I’m running ultegra di2 52 36 chainset and 11 28 cassette on my TT bike. Fairly regularly finding myself spinning out as my fitness improves and wonder if changing the front chainrings is the best way to gain a bit more speed?

I could accept a slightly higher, lowest gear if that’s the compromise.

Thanks for any input
