Here's gear 3 WOT
Your fuel pressure seems odd, goes down to fark all then recovers. Something is wrong. Where is the knock retard data?
yeah =\
Do you think that HPFP is the most likely culprit?
Some other guys in another forum suggest I start with new sparkplugs since mine have done about 45,000km.
I am looking at purchasing some Denso ITV22's. So I guess I will do one more test after installation and see where that leads me.
Can faulty spark plugs cause that kind of drop in fuel pressure?
I took it out (To save screen real estate) because it didn't show a reading at all. It was 'zero' across the whole log in every single log that was done.
Edit:
Knock retard was 'Zero' in data logs for gears 2-3-4
Knock retard showed figures of 0.35 in one or two lines in data logs for gears 5 and 6
fark, fuel pump is crapping itself, no wonder you're having problems... should never go under 1600psi @ WOT, and even at idle, should still be in 400-450 range
the pressure dies, AFR's go to hell, and throttle plate goes all funky, this is first step to causing a piston to appear outside your block, get new internals asap

suggest contacting @EdgeAutosport.com asap to get some, if they're out, hit up rallysportdirect, they get a shipment in this wednesday

Ok, just trying to pic up on a zoom zoom boom theory, it's worth monitoring at all times.
Sounds zzb to me.
my advice, get those fuel pump internals shipped asap, drive the car as little as possible, if you HAVE to drive it, baby it as much as possible...
get them installed, and then check fuel pressures again...
Thanks sarcasticone, do you think getting new spark plugs will do anything?
You are incredibly lucky...More lucky than you will ever know.
Personally I would not drive that car at all until you get your fuel pump upgraded.
That is a recipe for catastrophe in your log.
Changing your plugs wont hurt and get the NGK plugs over the Denso's.
this ^
spark plugs will cost an extra $40 on top of the $400 for autotech internals (or whatever else you get)
may as well grab them :)
but your #1 priority is getting the HPFP fixed asap...

if you havent already, go buy a lotto ticket LOL
The Denso's have had intermittent premature failure issues. The NGK's seem to be more reliable allround.
