a lot of bandits running that setup are in the mid 80's on their main. 92 is too rich most likely. advancing yr timing to 3/4ths to full might help a bit especially with a gap that small. also tuning your clutch would be good for you to. we have been running stock two shoes turned all the way in and then backed out 1.5-2 turns. we also have been experimenting with things other than atf.
