Default curious timings running ECM curves

Hello,

atm my computer run ECM curves with B1=11e6 at M2539 and M2543.
For M2539 prime95 uses FFT 112. One curve needs ~225 sec for stage 1 and ~76 sec for stage 2.
For M2543 prime95 uses FFT 128. One curve needs ~183 sec for stage 1 and ~72 sec for stage 2.

Is it possible to run prime95 with the larger FFT size at the smaller M2539, too? I could save ~40 sec per curve, and I want to run 2000 curves or so.
