A 460 is a 7.5liter V8 found in many ford trucks, thats what I got the MAF from. I don't need high impedenace injectors as I am have converted to low impedence injectors. Yes you are right about the timing issue with bigger MAF I noticed that with my buddies data logger. I plan on putting the IAT sensor before the intercooler and after the turbo so it reads higher intake temps then it really is getting in an attempt to retard the timing. If that doesn't prove effective on the data logger then I can always increase the resistance as well by adding a resistor in series with the IAT sensor. With the other hardware I already have there wouldn't be much to gain from a chip that I don't already have other then timing control. I hate the idea of hacking up the bumper but I don't think I have much choice, I just don't want it to look jimmy rigged.
