T04b V-trim, AFPR, 650's LOG...Questions!

[iiiwildfireiii]

I just installed my FIC 650's, 190 lph, and my Import Evolutions AFPR kit.

First off, the IE AFPR kit was VERY nice. It took me a couple hours to get everything setup, cut, and fitted, but EVERYTHING you need is there. My only gripe was the stupid stainless steel hose you have to cut yourself. It is really tricky to handle.

For my fuel pressure, I set the BFP at 43-ish with the vac line off, but when I stuck the line back on it dropped to 33-34 psi. I was under the impression it was supposed to be 38 or so. So, first question, which is more important? Having the fuel pressure at 43.5 with vac off or 38 with it on?

Now, as for the log: This was done at 13-14 psi on a T04b V-trim turbo. Automatic tranny with overdrive on from a 40 mph roll. For the low o2 trims at the beginning I was completely off the gas in order to slow down to 40 mph. How should I tune it? Take more fuel out or up the boost? And how much for each?

More Boost

Try like 16-17psi and see how it looks and then work your way up to 20.
