Default S14 SR boost problems , Help with my head ache please~!!!!

Ok long story short , I Just got done pulling the motor and replacing a few things in my S14 SR.

I put S15 Spec R 480cc injectors Into the stock rail, I cleaned them the best I could before install.

I have also replaced the S14 turbo for another S14 turbo that has half the mileage on it!

I get the car back together expecting to feel a little differance and the car runs like shit now, Seems like a boost leak, But I cant find anything. Breaks up around 5 psi and Up. Idles at like 1150 RPMs
Boost guage reads 17 Vacuum at idle.

Now, I have done a few SR swaps and Have pulled my motor and turbo multiple times ( gaskets and maintence etc etc..) And have had no problems like this before...FMIC does not leak nor do the pipes, I have a HKS super Seq And the knob on the back is all the way out....Well , Taylor..anyone , Please I just cant stand my car without boost...grrrr!

And I have used the search button with no real help first!

do you have a SAFC or some other fuel controler. If not your computer still thinks your 360's are in there and it will run super rich! I have the SSPL rom tune to help cope with the fuel difference. You didnt mention this in your post so im assuming you have not set your ECU up correctly for the 480's

there you go your car is running like crap cause you haven told your ecu that you have injectors putting in more fuel! Thus your ecu opens up for the 370's cc injectors worth of fuel, when you are giving it 480cc's worth of fuel. I recomend that you install atleast the safc asap so you can bring down the correlation. After that if you have more problems then I would look at other things, but I gauntee thats your problem right now.

Ok updated what Has been wrong with my car....GRRRR!
I have since RE installed the 370cc injectors and the car will not idle at all now.... The AAC valve is making a rather high pitch noise , like a electric motor..... Not sure what is wrong , But it has been about 2 weeks since I have been able to actually drive this car normal and I wanna burn it down.

we'll work it out, man. as soon as we get everything installed on it, i can run it across the street to the dyno and ill get ya all tuned up. youll just have to pay the shop for the dyno use (maybe $50-75?). but well get it running right

Problem is , Now the car will not run at all.... Only idles for a few seconds before it shuts off , And i cant even hit the throttle at all or it will shut down immediatly...I dont have a Tow truck at my shop and I dont have the time to Tow it myself do to my workload...This sucks, Well , Thank you Taylor I will be scheduling with you soon I just need to get her running , then let you handle the SAFC / MAF and tuning!

It's probably just running really rich it sounds like. I'm sure taylor can get it worked out. Heard nothing but good stuff about him =)
