okay so few months ago i scored a deal on a federal(not cali)pcm, and it has been one of the best mods i've ever had.I got it flashed and its worked since....now the problem is this... i just installed my pph headers, and its learned the curve fuel/air to the point where its smoothed out (aprx 220 miles) at this point..... BUT! now it seems that the shift points are back to what a stock pcm are... I can't even hit the redline (remember its a 5.2 auto) and i noticed its shifting is like what it was before the headers... do i need to take the negative cable off the battery to reset it or...? :help:
