Theres a boost gague as std on EscCossies too, i thought youd be used to one by now (you driver an esc cos right?).
dont know your spec, but id be guessing on that gague going to 1bar and being safe, but if you dont know the spec AND your still running it in then it obv wont be setup so get it setup before you give it loads or youl just blow the fucker up (and itl be faster once setup).
