What should the cat temp at idle be?
2017 and aero force gauge after 7-8 minutes of idling shows one at 1187 and the other at 1236. Not sure if those readings are correct but it’s had mods on it since I bought it 18 months ago and now about 750whp so wondering if it’s time for kooks green cats?

Given that the cat temps are calculated, and based on stock hardware, they’re most assuredly not accurate for the OP’s particular situation.
