Hey all,

I recently installed my Pure Stage 2 Turbo and it's been running extremely strong. It wasn't until I took a deep look at my logs that I noticed the MAF readings are literally off the charts, with it reading ~1180 lb/min.

Pure Stage 2 Logs:

OEM Turbo Log (a few weeks prior to install):

Interestingly, it just seems almost as if the sensor value is multiplied by 30, so 1180 lb/min would be right around 40 lb/min, which is around the max value that can be read by the M2 MAF. The values seem to scale correctly throughout the rev range without any hint of erratic behavior and the car has thrown no codes, no rough idles and AFR seems fine as well. Max value of 1181.5 lb/min is extremely consistent between the two Pure Stage 2 logs above.

So I'm just hoping this is just a issue with the datalog and not my car, but I figured I'd ask if anyone has run into this as of course there is a possibility my sensor is damaged (but extremely unlikely as I didn't even touch the MAF sensor as part of the install).

TIA

Thank you! I guess it was just a coincidence in timing, which is always nerve wracking when you make such a huge change. I'll definitely do that.
