Hey guys,
I went to the dyno this weekend to find out what numbers I'm putting down. I came out very impressed. I was thinking along the lines of 230 hp to the wheels. New Dyno Video 10MB At 17.5 PSI, I put down 246HP and 261 TQ. Just insane. Look at one of my run files below. I am still having trouble tuning my boost controller. You'll notice that after 4,000 rpm I have very strange spikes in boost. The theroy we have is, the controller is opening and then closing my waste gate door over and over after 4K. In the next few weeks I'll be tweeking the profec to run a constant number, then go back to the dyno. I believe I can squeeze out a couple more horses once this thing is set properly. ![]() If you have any suggestions, I'm more than happy to hear them. I'd like to again thank Manny, Jenn, and Dustin. With out them I would'nt be sharing this information with you. Again guys thank you, anything you need I'm there. 6GC. Without this place, I wouldnt have what I have. A thank you goes out to you as well. Thanks , DEF -------------------- ![]() I will return one day. |

DONT CRUCIFY ME ART, YOUR A NOOB!!! hehe j/k ![]() Is ChrisD running the stock regulator with an upgraded pump? If so, I think your right. There are a number of swappers, like me, who could not use the stock regulator because it allowed for a HUGE base fp. If he has a properly tuned afpr, I think there is something else going on. The regulator keeps the f/p constant to the injector so that the injector injects the exact same amount every time (at a given load and rpm). If working properly, the fpr does not allow more fuel to "get by". BINGO!!!!!! yes, from what i remember it was a stock fpr with an upgraded rail . jay, you are the only one who ever had his fuel pressure checked after having a walbro installed. for all we know, we all have the same issue you had and just dont know it. ...... this could explain the very ritch A/F ratio on some of the dyno sheets.
