I did not bypass the OBC in my setup as I have seen others do.
The pack says it will do 60A continuous and peak at 120A. Wondering if I am trying to pull to many AMPs at full throttle? Will a controller change fix this or possible a BMS configuration change? Any help/suggestions will sure be appreciated!!

Since the BMS is rated at 120A, most likely they have all current, charging or discharging passing thru the BMS. When you exceeded the 120A, the BMS shut you down. If full current from a hopped up golf cart is going to pass thru the BMS, it must be wired thru with at least #4 and be rated 300-400A. This is a much more expensive BMS that way. Check with them via email about options.
That is why the Zeva BMS uses the shunt or hall effect sensor.
I'll bet if you drive like your grandmother is in the seat beside you up to near max speed, it won't trip out. IMHO
