Does anyone know of a good tuner shop in DC/MD/VA?

So......now you don't need your car tuned? I'm confused with what your asking here, you have changed your mind from the original post correct?
If that's correct, how do you plan on adding the regulator? Also, I'm assuming you plan on running a 1:1 regulator, are you just hoping that you will be able to strike a happy medium between boost and fuel pressure so that the factory ecu will be happy? I'm just trying to get an idea of what your getting at.

LMS Supercharger (SS BD11A)
Synapse Engineering fuel pressure regulator part SC004
built-in 1:1 rising rate ratio
Built in 1:1 to 12:1 FMU at 1/5
Adjustable static fuel pressure from 16-100 psi
etc.
Walbro GSS342 In-tank fuel pressure pump
Fuel return system
Dyno tuning - never said I didn't need it, I just like that without a piggyback, IMO, the system seem more reliable. It's getting tuned.

I think the problem your going to have is that the ecu is going to be trying to run a target A/F that isn't what you want to run. In other words, your car has no idea it has a blower on it, it just wants to run whatever the factory NA target air fuel is, it's going to always be fighting whether you have a bigger pump and higher pressure or not. It's also going to fluctuate by temperature etc....(with air density) so say you get it spot on tonight, tomm when's it 90 degrees and 90% humidity (I'm from MD, don't you love the summer weather, LOL) it's going to be way out of whack.
By all means give it a try but it may not be as simple as you think. I wouldn't write off some sort of piggy back like an afc just to get you in the neighborhood of where you want to be. Also one thing to consider, IF you end up having to crank up the base pressure on the injectors, and then your running another 7psi more than that on them under boost....just remember those injectors were not designed to operate under those types of pressures continually. The GS has top feed injectors which don't get as much cooling from fuel as side feeds like a Supra for instance. Just something to jeep in mind if your base pressure needs to be set way high.

I would stay away from the emanage, when it first came out a lot of the FI Lexus people tried it and could never get it working correctly as it was still a piggyback and the factory ecu would still fight it.
Two options, you could look into a Haltech F10x (Excellent for FI on Lexus) or possibly contact Mo over at SRT and see if he can build you a custom "black box" for your application, similar to what the intakes come with, if you took your car to him they could tune the "black box" on the dyno for your supercharger application and it may be a cost effective way to go (if he will do it for you). I *think* SRT is a distributor for Haltech as well and I know Mo has done a bunch of low boost Supercharger applications so he may have some good advice for you.

OMG!!!!
Ray pulled it off and the results are more than I expected. Mind you, I only have suspension part so my car is stock, no Megan mid-pipe, no after market exhaust, 91 octane gas, etc. Here are the results
From 188.23/196-62 to 285.90/254.08!!!!
I'll have pictures and maybe a video over the weekend

What dyno did you use to dyno your baseline with? I'm assuming that you didn't have any go faster mods on your car when you dynoed your baseline so it must've been a mustang dyno that was used because the numbers are slightly higher than what a stock GS300 dyno at. Overall, good numbers to be had. Like you, I'll be finishing up mine in the near future. Base boost will be around 9lbs and max out at 13lbs.

looks like a dynojet dyno from the print out sheet.
Zippy,
I'm surprise from your base line that is running that rich in the 12 A/F. Good HP #'s from the s/c what boost is that at and what management system did you end up going with?
Make sure to have them give you a copy or dyno run file on a disk or jump drive.

ometimes. I posted the wrong dyno. HERE is the right dyno showing the correct gains!!

From looking at the dyno sheet, it looks like you're still using stock injectors and running base compression right? Since you're running low boost, I guess that you can get away with it. I like to play it safe so I'm running 440's and the supra TT gasket.
