If I go in the handling files of regular traffic cars and increase the power of each, will the ai automatically drive the cars closer to their new power limits during pursuits? Thereby increasing the speeds of the chases?

You could try to install a realistic handling mod for all vehicles. 

 

But overall you wouldn't get the NFS Hot Pursuit experience with GTA V.

For anybody wondering, I ended up installing this: https://www.gta5-mods.com/vehicles/faster-ai-drivers "faster ai drivers 2.2" and the mod works awesome! Pursuits are much higher speeds and the ai really whips around corners so quick that they sometimes outrun me! Wish I'd installed this sooner.

Thank You so much for this, I have hated being in a pursuit with a super car that a dump truck could maintain.  I no longer dread pursuit calls and have in fact installed more
