Thread: 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 ).

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

tunes make all the difference. glad you got it running right and it feels good to ya.

tune is seriously the best thing u could do! i don't have it on the gp; but i have a car that is!

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...)
