I am new to the is-f and perhaps the rear mounted setup is not a good idea, but coming from the turbo world and having seen many different vehicles personally running rear mounted turbos and even compound turbo setups successfully, I figured it might have worked. 
for the record on the dyno the ifs made a little over 500whp i believe. no dyno sheet posted but heres the run Lexus IS-F Twin Turbo Dyno Pull - YouTube
heres one making over 600whp Artisan Performance Twin Turbo IS-F Dyno - YouTube

How long have you been in the enthusiast game when it comes to cars and tuning?
6lbs of boost on a car that did not come with F/I and no tune......sorry the ECU can only do so much, but not working with 6lbs.
Also, you should really read up on other threads. I will type in cap's so you can understand this;
NO ONE HAS DONE A CUSTOM TUNE ON ANY YEAR ISF...............EVER.
There was a gentlemen on here who sent his ECU to a company who said they can tune it. They never sent back his ECU.
Another guy who did get his ECU back from that same company had no gains in hp/tq.
It's not unlocked. Check any major company who offers tuning for cars. The ISF is NOT on any list.
And yet....these ISF's with forced induction seem to be slower, cra_p-ton of CEL's........and no gains at all.
600hp ISF......show me a dyno sheet and a proper 1/4 mile video.....and someone actually tuning it...... I will bow to your feet and kiss them in high noon public square of your choosing.
The only performance mod's out for an ISF that actually give gains is normal bolt-ons. Cold air intake, headers, exhaust, and then a NOS of your choosing......

thats why they didnt post any dyno sheet, because they cant prove any gains on the turbo kit. Except the sound. If they were ever sucessful on turboing the isf's with proper tunes. A lot of members here would have that set up already. The best thing we have to reach 500whp is nos.

Thought it was a hoax? They did not really tune it just sent it back to the owner? And on dyno it showed a few hp gains....which could have easily been added due to weather and such....

Although I own a small plumbing business I went to trade school and took automotive to be a mechanic. Used to do all my own work but not so much anymore 
. Everyone seems to want to see dyno sheets so heres the one I have from my sti , car was a beast! For the record no hard feelings, I understand I opened myself up to criticism

31. owned everything from muscle cars(72 dodge demon, 72 chevelle, 71 camaro, 71 mustang mach1 with 351 cleveland, 68 chevelle) to 2 trucks, to a few different imports. Car I just sold was an 06 sti that I owned for 6 years and built the suspension, brakes, and had a completely built motor with a vigilant bottom end, blouch dom3 turbo and meth injection making over 400whp. Quite a bit quicker than the is-f but the is-f is such a great well rounded car that its made it a lot easier to forget about the sti Although I own a small plumbing business I went to trade school and took automotive to be a mechanic.

Also, the rear mounted STS turbos are not such a bad thing. While there is a bit of piping that adds to lag when sending exhaust to the turbos, there is the added benefit of cross flow cooling of the compressed air making its way back to the engine, acting as an intercooler. Then there is the issue of there not being any place to mount a couple of turbos in our cramped engine bays.
That said, I think turbos for the ISF are just a bad idea. I would love to see a super charger.

Not sarcasm...truth. Am I wrong that no one posted anything about seeing your dyno sheet on your STi. Don't be sad...get glad. Or something like that.
