You were mid 9s starting at about 5000 I think. I believe peak boost was hit right around 5200 and it maintained that all the way to 7000 rpms. I think be broke into the 10 psi range a couple of times but for the most part you were right at 9.5-9.9 psi. This is all baised off the MAP sensor on the UTEC and not off of the gauge. You were hitting 90% duty on the injectors by 5500and went static at around 6250. It is my opinion that if you advanced your timing a bit below 3500 you could pick up some power, and once you get the bigger injectors on you can richen it up a bit to around 11.7:1 and add in a little timing and you should see 500 whp. Tightening down that pulley made a difference too I am sure, belt slip is no good. Next time you are in there with the 550s let me know and I will come if I can. I think there are some improvements to be made in the lower load ranges for sure!
