I know there is probably a thread regarding this issue but seeing as i never ever post. I figured id pull a newbie and throw up this thread.
So here it goes.
New intake its one of those super short Turboxs deals
New injectors are the 565 injectors from an 07 legacy

Now i know you are suppose to do one then the other but seeing as the guy helping me with the wrenching offered the injectors as a You might as well do it while we are ripping out your TGVS i figured.. bah ill figure it out after.

Well its after... I threw on the Latency and Flow from an 07 legacy gt and a very rough maf scale
Car drives
But im getting FLKC and FBKC and my IAM is down to 15 from 16. Afr showing on my wideband jumps from 14.3 - 15.6 at idle and sticks around 14.7 - 15.2 during cruise. Not to mention the huge flame i shot today made me think.. Well.. i could use some slight help lol

"o and i did notice that after i just rev the engine the AFR hangs at 16 for a second then drops back down to 15.2 at idle"

Im wondering if one of you fine chaps can point me in the right direction. How shall i go about scaling both of these while both are installed seeing as i do not have access to a full stock airbox.

Cars an 02 btw so 16bit definitions.

Any help would be awesome.

The correct approach is to scale 1 at a time. Put a stock intake on, scale injectors, put new intake on and scale the MAF.

But if I had to do this and I absolutely couldn't get access to the stock intake then I would probably get the stock injector values from the 07 legacy and plug them in. Then scale the MAF.

You may want to pull some timing, lower boost, and change OL fueling to run rich so you don't pop your engine. Also check your fuel trims if they are +- %15 then you are definitely running rich or lean. With the new intake it sounds like you are running way lean.

I have an 02 hybrid swap that had the exact same MAF tube from TurboXS that came with my SSAC FMIC years ago. I was maxing out the voltage on the sensor with my setup and measured it to compare to a bigger MAF and found the TurboXS MAF housing is actually the same as stock..

I don't see why you couldn't just use a stock scaling for your MAF and and just tune the injectors in..?

Casey has a tweaked base table for our model car's housing over at viewtopic.php?f=31&t=3292

Compare that to what you have, give it a shot..
