Got the good stuff in there.
So - Just read that whole thing...and now I'm curious. How far will the OEM FPR connected to the boost port compensate? I don't want to have to put an adjustable FPR on my list, but I want to make sure I do it right...

Not sure what the end capability of the OEM one is specifically. I don't think there is any test data on it. I do know that the diaphragm of the OEM one is miniscule at best.

I do know of two trucks, at least, which are running/ were running 10 psi boost on them. One still is. How well does it work? Well enough I suppose. Better than nothing, that is for sure. How much more can it handle above 10 psi? I don't want to be the guinea pig...


Here is some additional reading.

Hmmm-I don't suspect I'll be all the way to 10 psi. Might have to see what the dyno says before I try any swaps to adjustable FPRs...

If you are going to be using the UCON, I can pretty much guarantee that Gadget will say not to do the FPR mod. Basically because the tune is setup for static fuel pressure, w/ the specific sized injectors that are being used.

Having a larger diaphragm FPR still won't hurt though. If you had a different tuning device, I would say to use the FPR mod as well.

Thanks everyone, I got it all hammered out, let a local custom muffler shop install a bung at the end of y piple like the one above, it was 30$, so now my boost gauge and AFR are working properly and can be swaped back and forth between the 2 DM-6's on my dash board... thanks for all the help...

What should i be seeing for afr at full power in the top 2 gears? its running quite rich... above 50% throttle in 4th and 5th gear afr drops down to around 11, i have seen it drop all the way to 10...

I called TRD and went by the local dealer that installed it all as trd suggested and verified that they flashed the ECU, I was told by PLX and one other custom toyota shop that TRD could send them a custom flash... waiting on the local dealer to run diagnostics on it...

forgot one question, anyone know if the PLX DM-6's have adjustable brightness?

normal does not = acceptable...

i know they air on the side of safety, but if they offer a free custom ecu flash I'll take it.
