dyno tune happening tomorrow 
took a spin around the block with light throttle...wow, car is already totally different.
some golden shots right here:
done up engine bay
30 degree merge. beats a Y-pipe anyday
now i can really say i have a full 3" exhaust cuz it's 3" right after the merge!

cat? what cat? lol
stock 3vz has only one cat after the y-pipe.
and the sensor you see is not what you think it is, take a guess.
no CELs, never CELs on a 3vz

Don't know you could supercharge a 3vzfe es300 something about the manifold thought only the 1mz would accomodate The trd setup. I would like to know how you made it word i have a 93 es300 130k 1 owner car.

car is tuned...**** is amazing...but i feel like being an *** cuz i'm tired and still recovering from a summer cold... my numbers are staying secret for now
but, i'll post something that might confuse some of you.
i switched from a 6psi pulley to a 8psi pulley. previously, the peak boost measured at 7.5psi. now it's only measuring at 7psi and the boost dips. this could only mean one thing and it's a good thing
take a guess haha
oh yea, btw, that sensor is a AEM wideband

Guess. Hmmm. Normally, looking at the manifold pressure, I'd say that there's an intake restriction limiting the amount of air volume to the supercharger. But no. Since it drops off, there's something even better happening. Better exhaust scavenging of the cylinders at high rpm. The engine is actually being vacuumed downstream with that new header and collector arrangement.
The engine is breathing better only because the exhaust pulses are pulling out manifold pressure. Could there be a bit too much overlap from the exhaust and intake valves requiring a cam regrind?
But hey, you're going to a twin charged system so that will only mean it will be pulling more intake charge at higher rpms, which will be at a higher pressure courtesy of the supercharger and turbo charger.
Nice setup. Killer exhaust.

Don't understand your lingo.... you seem strange to me sir.
Really though I don't know what all that talk means but sounds like your doing a GREAT JOB. Congrats!!!

So with this setup, are you planning to do a cam regrind? Are the intake valve and exhaust valve overlap published, and if so, how many degrees do they overlap?
With such an efficient exhaust system, the exhaust valve could close sooner so that it isn't stealing intake manifold pressure and dumping it out the exhaust as well. That should result in a better charge in the cylinder.

didn't make it to 300, but sure was close. a huge fat torque gain all across. I'm already very satisfied.
comparison to the first sc setup (the old graph showed only 240, got 249 after full tune)
here's a bonus video:
