not enough information.
What 850cc injectors are they?

Don't have any experience with them. I shy away from side feed injector tuning.
I don't know the correct scalar or latency, but you might also need low injector pulse width compensation.

Finally was able to pull the stock ROM off the car does anyone have scaling data for the SPT intake for the '05 Legacy GT 5MT? Not sure where I should start with.

as per my response in the other thread, easiest way if your just getting started is to do one - adjust the map to suit, then add the other. Probably as handy do do a run, log the actual AFR on your wideband then fit the injectors and adjust the injector scale value until you reach the same AFR again. If the airflow corrections are off at idle then increase/decrease the injector latency until you are back where you where. After that add the intake and do some maf scaling until your back where you where and you should be good to go.

Good luck and may the logs be ever in your favour!

Can't I try to get the airflow arf to be as close to stoch as possible at idle as it is now?

I got it I forgot to post it was the injector latency that needed to be changed I changed the 14v to 1.50ms and it idled fine

ok I'm pretty some one of the fuel injectors have crapped out.. this is what I noticed normally idle at 14.7 or so.. now it would be 16+ AFR.. but while in boost around 15 or 12 AFR.. at idle the AFR would be always jumping up and down at least 8 points..
Today when driving on the highway I give it some fuel and I had a huge loud bang and my AFR is full rich at 10.0 AFR no hoses that I can see have came off but with it running full rich it has to be a fuel injector issue?
I noticed the 2300-3000 RPM range I had a a lot of hesitation that would cause the car to buck in the lower gears no matter how smooth you tried to roll on the throttle.
If I don't have to work tomorrow I will try installing the stock injectors again.
