I'm suprised all these "prone to failure" parts survived on my tuned car given the 1/4 mile runs I have done too.
I sent my logs to Buraq and he reckoned car is running too rich so I may send him some new pulls once car is back on road. He thinks the drop off in lpfp may be tune related too. I thought a 11-12 afr target is appropriate unless im missing something. My local custom tune had a 0.88 lamda value on the e85 tune (this is a standardised value that doesn't require transformation for different fuel i.e. 98 vs e85). I will try and get the basic things sorted first then look into tune again.
cheers will keep everyone posted

My car is a Sept 2006 model and I am still running the original hpfp and injectors. So far I have had no issues with these after 127,000km. I cannot see how your hpfp would be contributing to your issue. As you say your AFR results are no problem. A faulty injector should be throwing up some DTCs I would have thought.
