Okay. I'm not sure who needed info on the upgraded STS intercooler, but since CIN Motorsports already posted preliminary pictures, here are some detail and comparison shots. The new core is both thicker and taller.

I turned the boost up to 8 psi from 7 psi. Now boost is rock solid. No more minor boost spikes.
New problem however: knock! I suspected that I would need a new tune after I installed the BCS.

Short video. Not really wide open throttle but that was to about 85-90 mph
The idle is funny because I just started it and my fuel pump is a little twichy.

Finally got around in getting my HFC and Y-pipe installed with a new tune. I wrapped the cats and Y-pipe with heat wrap but did not get to wrap the mid pipe (ran out of wrap). Once I wrapped them I dropped my car off at Functiontuned for the install and dyno.
My car is a 03 G 6MT. I installed the kit myself in September 07 and got it tuned at the same location.
My final results were 355whp/350wtq @ 7.8psi. The red line depicts the before, and the blue is the after. As you can see the power band is a lot smoother then before along with the tq. Overall I’m happy with the results and enjoy the car more then I did before.
Few things that I have to address in the near future; One would be a new front bumper b/c I still have the stock one which is killing me. Two is an EBC b/c my boost is not stable thought-out. Three, at some point I have to get a fuel return or bigger injectors b/c I’m almost maxed out and with cold weather I will be (lucky for me it’s starting to get warm).
As most of you know this kit is not that great (consistent) on the dyno and tends to become heat soaked.
Here is the HP/TQ before/after

Thanks Jeff.
They are FI HFC. It did make the car significantly louder then before. I don't know if it's the combo of the two (HFC&Y-pipe). I will get a video this weekend.

Do you have a Boost graph? What WS spring are you using and are you holding boost until redline?
Edit:
Is that dyno Raw DD numbers? Mine is DJ corrected so you got some good #'s there if there is no correction.

I have the .3bar WS spring (4.3psi) and I have trouble holding boost at 8psi. I was told that you don't want to run double the amount of PSI your WS Spring is capable off. Can you find out if you are holding boost all the way to Redline and do you have the .3bar or .4bar WS spring? I just ordered a .5bar spring and hope that fix my problem, if not then I'll go ahead and upgrade my FMIC... Also what RPM do you hit Full Boost? It look like around 4200rpm.

Sorry for being so vague on some issues. This is not my DD, and I have not driven her much since the new tune.

I now goosegoose use to have the same problem (boost dropping on higher RPM) and he also has the .3bar spring. I didn't know STS come with a BC!! Do you have pix of this unit?
