Hey guys, I am buying a complete TPI system and have the choice between map or maf systems, can someone tell me the differences between the two and the advantages or disadvantages of either one. I need to let the guy know tonight so help soon please.

thanks,

 

I would suggest doing a search as this has come up before. But MAF is the best ticket for the average car, that is why all modern performance cars use MAF. MAP is for speed density systems. If you have a DFI system and a laptop then speed density works better as you remove the MAF sensor restriction.
