my o2 reading on powerlogger seems only to work in 1st gear the it goes down to .05 and stays there till i let off,also the maf readings at ft would go upto around 450 now it gets pegged out at 284 on powerlogger, my setting on powerlogger is set on 512 for extender chip, any ideas thanks , would the rjc power plate i installed have any thing to do with these lower readings
