Got mine last night, fired it about 10 min ago. Gonna idle 2 tanks, putz it around the track for 2-3 more then race tune it and race the F%%K out of it tonite..........MBX6/OS 2060, If it doesnt have enough bottom I'll put a OS 2050 on it. Maybe a 053 dunno yet. Will update later. Tired of wasting $300 motors club racing......
