Default TC Mod esc setup advice for 7.5

I run USGT but like to venture into TC mod. I'm starting with 7.5 motor instead of conventional 4.5 to 5.0 turn. The track I run at is fairly large black CRC carpet. My esc is HW XR10 160a. I can't find any esc setup on petit RC for 7.5 only 4.5 & 5.0. Can someone give some baseline setup advice regarding boost and turbo, I assume it would be more than 4.5 & 5.0, but how much more. My motor (McClan) can timing is currently set @ 20.

My FDR will be around 6.5 to 7.0

Since you are looking for less motor than a 4.5t already I would just duplicate a typical 4.5t setup the the 7.5t. No need to push a 7.5t hard when you could just put a different motor in.

Honestly, start with the box setup for the ESC and have fun I think that setup is a fair starting point.

Thanks I'll do that. For USGT, my rear toe was -1 and 0 toe in the front. For TC, I notice most are running a much more grippier setup, like -3 toe in rear and 1 to 2 toe out in the front, camber also seems to be higher with TC mod. Belt tension is also tighter with TC mod. Is there anything else I should be aware of when transitioning to mod? For example, should I go thicker in the rear diff fluid. I'm using 8k now for USGT. I was also told not to glue the sidewall in the rear, only front for mod.

It is very rare to glue the rear tires in most conditions.
Generally, 10k in the rear is a good starting point and helps smooth out the car.
