I'm trying to adjust my d-specs to get a close to stock feel as when i had my original springs and shocks (non-sport). just wanted to know what you guys with revised springs have used. I tried 5 turns from stiff front and back and it was way too floaty and bouncy. 4 turns from stiff front and rear was way too stiff.

I'm currently using 350/coupe springs and new d-specs for a 350

It is between 4 and 5 indeed, but your tire model and tire pressure would matter too. 1/4 turn make difference too, so keep playing with it, you are in the right range. I am at 4, but I prefer stiffer setting.
Try tire pressures 30-36 psi cold
