Dynoed My car 5/30

I Made a best of 245 horsepower and 326 foot-pounds. I'm pretty happy with those numbers. A friend of mine helped me tune via my wideband earlier this week.

Here's a video I threw together really quickly (New video, audio track was disabled)

YouTube - Grand Prix GTP dyno

Here's the chart:

The guys were really impressed/surprised by how consistently it ran and said that we did a heck of a job tuning it. The AFR looks great, no knock except 2* on the last run (coolant got up to 190*, it was getting heatsoaked, 148k miles and I've never flushed the coolant :th_doh.

I'm very happy with the results though. The tune really changed my whole car, it honestly feels so much faster it's amazing.

Thanks. It's so great tuning on a wideband. the wideband Dyno Brian used was dead on with mine too, which is nice to know mien is accurate. The new tune made the car completely different. I can't believe how much better it feels now.

I also went from getting 25mpg's average on my way home from work to about 33mpgs (75% highway, 25% city, also taking into account I have my stock wheels on again and not my heavy ol' 18's, which I'm debating putting back on...)
