Brushless help

[supraracer]

Ok well i recently installed a mamba micro pro 8000kv set-up in my mini-t with a 11.1v lipo and im not sure whats wrong but the first day i ran it, it was very quick ( not as fast as i think it should be never had a problem with wheelies or anything) But the last 2 runs i did with a fully charged battery it is very slow and will stop and go when it pleases.
This is my first brushless car so i could use any advice.
Also it is pulling left, camber is as close to 0 as i can get (free play in the parts i cant seem to get it straight up) Can i adjust that on my Tx? Im pretty new to all of rc.

thanks for the advice
