My MAF sensor is maxing at 5-V around 3/4 throttal. With a tune from Sal will I be ok or do I have to replace this?

 

What tuner do yo have?

 

The stock 90mm will peg 5 volts in the 425-450rwhp range (depending on mods). You cannot change that with a tune. If you are pegging that quickly, then you either need an SCT BA2400 MAF, or an MAFia extender and a retune.

 

there was a couple 2400 maf's on NLOC classifieds yesterday. Just a heads up.
