If you need a shorting bar, let me know, I've got a few of them. I will say from personal experience that mine was missing and I was getting around 10MPG. With one in, it is at 12-13MPG. I'm sure I still have engine performance issues but what you gotta think of is "why?". Why was it removed in the first place? In my case, it was due to severe engine pinging. I can run with the shorting bar in place and with premium gas and get the occasional ping on a hot day under load or remove the shorting bar and use cheap gas but it still pings. I think it's more of a problem with the early PCM's in lean burn mode once the transmission shifts into OD, it will immediately start pinging. So you're going to have to run some tests to see if you have to run premium or if you want poor gas mileage.
