More a curious question than anything.
Is it common place to tune the MAF of a dead stock car? Are the minor dial ins worth it?
I was familiarizing myself with the software on my 09 G8 and I found that when I logged MAF HZ vs STFTs I was seeing a +- 4 or so over a wide range . I did a lengthy log and multiplied % half and saw them come in around +- 2 and in many ares +- 1 or less.
Would that be normal or should my factory tune have been closer than that? (Stock car, Stock Airbox and Clean Paper Filter)
