So I will start by saying, after having all this stuff apart on my bench for months, I think I finally found the golden ticket. Funny thing is, this ticket turned out not to be one thing, it turned out to be a combination of things that when addressed have shown some serious promise. Once I thought I had it figured out, I Basically took everything off the test (stage 3) car, made my modifications, and put them back on. First I was hoping for normal start up and idle, check, next I started with stock tune just watching the live HPFP data on the AP. Things seemed normal, so I loaded a more aggressive map, same, finally I loaded the map we ran the 572 on the dyno with the HPFP dropping under 1000 PSI and staying there and fuel trims maxing out from about 6 grand on. This map has been 100% unchanged since dyno day. After loading the map I did 2 pulls back to back and checked the log. HPFP and trims to my great happiness were both completely on track, HPFP took a dive for a small RPM range when boost got heavy but recovered almost instantly and held to redline, trims were negative. I followed this up by 2 more runs tonight with the same results. So what this pretty much tells me is, we made 572 with trims nearing max on 91, we now have negative trims, I have no idea what this combination of modifications will net as far as HP, but it seems 600 on good pump gas is not out of the question and with race gas, you are golden to at least that. I plan on offering the upgrade on the fuel system components on a mail in basis but not until I thoroughly test it on all fuels including E85, so it will be a little bit. Once I can get some miles on the parts and make sure they really are going to work for more then a few pulls I will be a little more confident, happy but skeptical at this point. This is the first step, but it is a very promising one. 6 months in and breaking down the N54 walls one by one.:music-rockout:
