Hi all.
I have been reading this thread with great interest, probably going to create axiety with regards to my gear box.. but that aside, what do the abbreviations MAF and TP stand for.
Here you go fill yer boots.
Following is a comparison of the previous standard and the new standard. New Standard Previous Standard
