On the sniper that’s the iac motor not sure if that’s the same as the Atomic . On the sniper it needs to be adjusted when the engine is hot between 2-8 it needs to be in that range in park or neutral . By turning it clockwise will lower it anti clockwise increasing but you need to keep an eye on the tps as if it goes off 0 you need to turn the engine off and restart which will reset the tps. Wait for 10-20 seconds before adjusting again. If you have an electric fan you want to do it before the fan kicks in as the iac will increase to compensate for the extra load .
