www.dynamicturbo.com lists the SAFC for $299 with the subtitle "we will not be undersold" I know that this will make more power! It's like the MAF optimizer, just way, way, more adjustable and with many other features. I've been eyeing one up for quite some time. Once the next round of mods goes on the car (65mm TB and Big MAF) the SAFC will go on for fuel tuning along with the 100k IAT pot for timing control. Bwaahahah... (evil laugh)
