Thread: HELP! Need formula for changing maf's

I've already got my proper vq map switch over but im stuck on the formula to get me in the ball park.

Ive used the injector change formula with great success.

Do i go by maf hp limit or my maf size? I think you go by the maf hp limit.

ex: (n60 maf)=325HP/(stock sr20 maf) =250HP which equals 1.3 then multiply by my k value?

Please helps guys

Yeah you go by hp limit, and fine tune from there.

Keep this for future reference. Alot of helpful info.
