So i made some changes.
The MAF sensor holder is from a TRD CAI. I wanted to dress up the bov and keep it recirculating. The Tial reminded me of something
so there i went. I installed the CXracing 3" exhaust. had to cut and splice the s-pipe in three places, but the rest of it fit just fine. After a fresh tune from Tony at UMS she put down 285whp at 6300 and 10psi.

Hey Madmarx, a question... when you floor it at low rpm, does your engine ever bog before taking off? Mine does and I haven't been able to tune it out yet. I suspect that it might be related to the much greater distance, post-maf air volume and restrictions between the maf and TB. I'm curious to see how many others with draw-thru maf setups have this problem and if it can be tuned out with a piggy-hack like the FIC. TIA.
BTW, Happy New year!

It will bog coming out of low idle off the line. I avoid this by feathering the gas pedal. I can't floor it though, or my wheel will just start to spin. At 3000 rpm the boost is at 8.5psi. I can't use the whole pedal untill I'm in third gear. However, I can floor it in third, forth or fifth gear with no bogging issues.
I still get error codes for random cylinder misfires. The freaze frame data has the misfires occuring at low rpm, low velocity at idle or just comming out of idle. If im driving on the highway, no error codes. In the city, code after 50 -90 miles.
The idle bounces around a little but will stabilize in a couple of seconds. I would like to be able to just turn it up a 100 rpm.

Where did you get the rad hose? That's cool.

Its is both hoses. Strange, but anymore 120 is just a drop in the bucket. If you want a real shock think about how much i spent on the battery LOL. I must be insane. Its possible the car has control of my mind forcing me to mod
. Yep that proves it I am insane.
Whats that car? brakes, lsd, tires, turbo upgrade? Elvis tattoo...come on anything but an Elvis tattoo. Doh, car wins again.
What? I already said im insane.

$120 for BOTH hoses makes big difference. That's not so bad. I thought it was only one hose since the other isn't pictured.
I feel ya on the money pit aspect of this. I can hardly believe that I've invested over $5k into a $17k econobox that's now worth $10k trade-in and still needs about $3k to be finished. I'm really torn right now about whether to continue or cut my losses.

Soo...I know I'm SUPER late on this...but did you have any trouble tuning with the cone filter and scuba delete section?
I saw that another descendant xb2 owner got MAJOR boost creep once he changed out the stock air box and scuba??

There are quite a few scan tools out there but the most widely supported is the ELM327 chip. The genuine elm327 chip is available from scantool.net in their Elmscan 5. Nice unit but a bit pricey at $110. There are a lot of elm327 clones available from ebay and elsewhere for $20-$100. I'm using a well-made clone I got for $40 shipped from dealextreme. So far it's worked with every OBDII software app and 1998-2008 Dodge, VW, Toyota and Scion cars/trucks.
AFAIK the FIC should have included a USB cable to connect to your laptop. Most scan tools include a OBDII port to RS232 cable that goes to the scan tool and a RS232 or USB cable to connect to a laptop. I much prefer USB to the old RS232 serial port. My netbook doesn't even have a RS232 port.
Connecting a laptop to your FIC will allow you to data log the FIC and UEGO (if connected to the FIC), tune and possibly monitor the FIC connected engine sensors. To interface directly with your ECU to monitor all engine sensors, read and clear codes, data log O2 sensors, fuel trims, etc. will require a OBDII scan tool. In short, you need both.
Rather than go on and on about the various scan tools and software, I suggest you check out the following links and feel free to pm me with any questions. It's pretty cool to monitor every engine sensor in real time on a laptop.

You can do a little more sanding on it and some paint and it would look nice. No time for that now but I got that in schedule.
