The stock MAF is probably good for around 500 rwhp.

 

In case people are wondering, changing the diameter of the tube the MAF is placed in changes resolution. I had my factory maf in a 3" diameter tube, and it maxed out at like 4500rpms at 4psi on a lq4. Other people have had different results.

I wouldn't spend the money for the silicone couplers and t bolt clamps if I had it to do again. Go ahead and go SD.

 

It was on a dyno about a year ago to get tuned with the 7lb spring and ran out of fuel. It's good for cruising at the moment but nothing near wot

 

Ohh ok gotcha

 

I'm pushing 8-9 psi out of my mp122. Ive seen as high as 11,200 hz .... I'm going sd this summer.
