So I finally got around to getting my air to fuel ratio gauge installed this past weekend. As I had previously had a Perrin intake on my car, but subsequently took it off due to fears of running extremely lean, I wanted to do a little real life experimenting.
After getting the air to fuel gauge up and running I did some stock readings. The car was running at 14.5-14.7 at idle. I did a few wide open throttle pulls and the ratio dipped down to 11.0 - 11.2. After this I re-installed the cold air intake and found that the car was again running at 14.5-14.7 AFR at idle. Low and behold, at WOT, it was also running at 11.0-11.2 AFR. Flashed to stage 1 and the readings are about the same.
I think my next upgrade might be a manual or elecontrol boost control to see if I can get the AFR leaned out a little (high 11's maybe?) to get a little more power, as 11 seems a bit rich.
