Avoid anying N1/N2/EGT spike after start-up

We all know how bad the start-up sequence is with FS. Once you add fuel at approx 20% N2, the N2, N1 and EGT peak at ridiculous values making the combustion part of the start-up sequence extremely short.Is there any way to avoid this without changing the N2 spool times for higher RPMs to abnormal values?
