bummer on tipin. the WRX ECu doenst have enough raw tip in adjustment so i'm using both A and B maps with lots of value.
i just scaled the upper ranges of the MAF down ~5% after that log, and i think that's my final values, and it was 1.61 at peak but yeah. that is reasonably accurate. below 3.8V MAF my AF correction is +-<7%
i expect more when i get rid of the high 110-120F IATs from my intake terminating in the bay. i had it going to the stock airbox, but that was actually a restriction and a friend needed it.

i know it doesnt look liek much.. hah not in that pic is anything recent.
i did a lot of headwork, and some manifold porting as well. even running an STi oil pump and block oil passage smoothing
i dont think i have headwork pics(cant foto and work at the same time and i'm always short on time)
have a look:

http://www.rs25.com/forums/f145/t120446 ... agnet.htmli have my friends GC(topscoob#011) i'm making an oil cooler duct for right now, and i lent him the wagon. i should have it back tomorrow and i can get you any data you could want to validate this. i'm not full of s*** or just bragging.
a small aside, that same duct is going on my car but to the airbox i'm still working on. ram airbox i prototyped on my STi is worth ~4psi in the manifold ~120mph the VF39 wont deliver at lower speeds, so i expect to see ~1psi in the airbox, and that's another 20-30 hp.
