Hey Guys,

I did the bm3 stage 1 tune. My charge pipe blew up and damaged the MAF sensor. The dealer wants $400 for a new maf. Do you guys know where I can get a aftermarket one for cheaper? Or used?

Thank you

You mean the MAP sensor. MAF is on the intake pipe. Have you tried your local scrap yard? I bet you can get one for 50 bucks there. Consider getting the N20 version so you are ready for a future turbo upgrade.

Thanks, why can the n20 hold more? I think normal is 3.5 bar, is that one 4 bar or something?

Also, is it just plug and play or do I need to do anything to let the dme know if i go with the n20 version?

There is a setting in BM3 to use N20 TMAP. Not needed unless you go above 20psi though.
