Drive it normal. But, if you go WOT, it may be lean. The LTFT's will update over the first 100 miles and several key on/key off driving cycles. Get into it a little though. That way the cells under load can learn too. Once they do, the positive fuel trims will transfer to WOT and add in some extra fuel. Keep in mind, it still could be lean. You really need to find someone with a scanner and a WBO2 to be sure.
