esc boost setting help 2wd indoor off road

[wookieewonder]

Hello. I'm looking for some advice on setting up the boost settings on my esc for a tight off road 1/10 carpet track.

1/10 2wd (hobao h2 with an 21t pinion 76 spur giving an FDR of 9:1) 8.5t brushless (3980 KV) motor, 2s lipo, Turnigy trackstar esc 120amp.

The motor has a minimum of 15 deg endbell timing (current setting)

Boost timing set at 15 deg

turbo set at 10 deg

Boost start rpm 4000, boost timing acc 100rpm/deg, turbo slope 18/deg/0.1s, boost delay 0.25 sec.

At the moment it goes like S**t off a slippy shovel, bags of acceleration and temps are fine after 6 mins. Worked well at a larger outdoor astro/grass track.

The settings I need some help with are: Boost timing start rpm (4000) and boost timing acc (100rpm/deg).

Do my settings look right for a tight indoor carpet track with jumps? Thank you!
