Hey I just wanted to give you guys an update on Mark's car and also ask some questions. Last night we replaced one of the O2 sensor dummies and got rid of the check engine light so now it should be running to its full potential and we are ready to start tuning.

My first question would be, with the 3.0, are we maxing out the stock MAF sensor flow wise? I wouldnt think so but a lot of the hybrid guys are running bigger MAF sensors and I wanted to know why.

Second, What should we use as a tuning tool? We will have a Wideband O2 sensor so we'll know exactly where our A/F ratio is at but what would be the most cost effective method to tweak it. The three options ive seen so far in my searching is to use the MAF Calibrator from Pro-M, The Greddy E-Manage that warmonger is using, and having a custom burnt chip. Mark was saying their is a guy who custom burns chips by your Dyno graph. Is that the way to go? I would think even after a custom burnt chip you would want something to be able to tweak your A/F a little bit because running on the dyno has a different effect than running on the street.

Let us know what you think guys. Thanks.

Hey also can the SAFC be made to work good on Contours?
