So guys! I have a 4banger 2wd Tacoma. Is it normal to be in 3rd gear, at 6k rpm almost flooring it? Going 65-70mph on the US-395, going up the grade to Mammoth Mountian, at 7 thousand something feet of elevation. Considering the oxygen is thiner here. Im really considering about a regear! If so what ratio should I run? I'm running 32” Falken Wildpeak M/T’s.
