setting up a 9xl

i just got done with my revo and its got the 9xl motor. its geared 19/36 on a 3.3 tranny. with foc.

i drove it for the first time today and it was fast but did nothing but wheeles lol. it was cool but i want to fit the full speed lol. and its hard to cause it always does wheeles. even when i slowly go up to speed and then hit it. it still does a wheele lol.

i was on my computer trying to set the mamba max up and i sow you can move the throttle curve. i was just wondering where would be the best place to set it . also should i keep the motor timing at the lowest cause thats where it is at now.

thanks.
