It does increase signature radius, but it can be mitigated a little bit with not using a gabillion shield extenders.
I did use one, it bloomed the sig radius from 213 to 276. If I’d not used extenders it’d have been around about the 250 mark, but lower EHP.
The comparison of the two ships is:
Cyclone FI - 31.4k EHP, 347 EHP/s for EM / 39k EHP, 432 EHP/s for Thermal.
Augoror NI - 28.8k EHP, 323 EHP/s for EM / 22.3k EHP, 250 EHP/s for Thermal.
Although I will say I plugged in 100 for the Augoror armour regen, I was getting about 89 hp/s on my fitting window and I just bumped it to 100 for the booster, so that might be wrong as I have no idea what implants you were using.
Which is why I was curious how yours held up against the BS + Wave. The cyclone was just for shits and giggles because that’s a ship I’d used to go roaming for reputation fixing, I just pulled off some of the mid slots and slapped on an extra recharger and amplifier and swapped out to HAMs, despite my horribad skills in them.
