I eventually want to switch to TPI on my elky. My question is what is the difference between MAF and the speed density. I heard speed density only works with 700R. The MAF looks kinda ugly (but then again I have a hood to hide it all. lol.) also I know the speed density has something to do with the speedometer or something like that. I eventually want some type of forced induction and the MAF wouldn't work. I need the earlier TPI but does it have to be converted to speed density so i can put on a forced induction (TT, projection etc... .). Will it work?! I've seen it but EXACTLY how is it done?
