Want to build costom turbo kit. Need advice from boosted guys!

Well for a long time now I have been trying to tune my FIC for 20psi. I have never been able to get it quite right. Because of the difference in fueling from the factory computer at say 60% throttle opening at 10 psi compared to 100% throttle opening at 10psi. If tuning for 100% throttle you will be very lean at 60% throttle. If tuning for 60% you will be pig rich at 100%. I have tried to find a happy balance but its just not possible. I have turned the boost down to the 12-13psi range. This is a little bit more managable. To get the full potential of this built motor it will need a stand alone. Its just more then I want to spend at the moment.
Just curious how does the boomslang hook up to the AEM EMS and the factory computer at the same time. I now the power steering still needs to hooked to the factory computer. Also can I still use my A/C. Anyone know?

I am wondering this as well. I REALLY want to stay away from AEM again, but may end up having to go that route. I know there are plenty of folks that swear by them, but I have had too many issues to not be leery with their products. So I would like to know whether or not I would still be able to use my Bslang or if I will have to pick up a new harness also.

During our phone conversations I was afraid of those issues you are seeing with the FIC just not being able to cut it. To me the FIC is really just a hobby box with how intelligent and restrictive today's ECUs are from Toyota. Best to just bite the bullet and go full standalone otherwise you are just wasting your money every time you start your car rolling down the pavement.
