Yes i searched... a lot.
So i have a 2008 2.5i and i have some mod's on it, a lightweight crank pulley, a custom sold air intake, and a cat back exhaust, im not staying N/a for much longer but i need some help figuring out how to tune for these mod's and ill need some help later once the turbo block and parts are in. Yes i have really really searched for like month's for how to's or ways to tune it in with my tactrix 2.0, i understand what alot of the values and tables are for but not all of them or enough i guess, at the moment i have a CEL due to how close the MAF has been moved to the throttle plate is there anything i can do other than move the MAF? I have really really really searched and i am clueless at this point so any help would be awesome.

Dang i forgot to update, p0171 code apparently im lean... >.>
i searched high and low for a hole or a leak, with smoke, and carb spray, No success, I have the snorkus in line in it's oem placement, and as for the MAF im thinking it's pulled up out of the flow too far ATM i had a solid piece of molded PVC (no not Homie Depots) with a velocity stack in itand it never threw a CEL but it was the same inside diameter, as is the current one as the stock intake, the main reason for all this aftermarket buggery is for a perrin high flow foam filter element( i off-road in the mountains often) which is awesome for fine particulate and high flow. So basically I really have no idea where the lean code is being caused other than maybe the maf sensor being A) Dirty B)Out Of the flow C)something is Actually wrong with my fueling. As it sits now i have 4 reflashes on the 32 bit? CAN-bus system, mod's in the inector size (wrx 560cc blues for E-85) the rev limiter 6250 rpm fuel cut, and i believe some random G/s mod's because at one point there was a problem with the Head's vent hose being off and i didn't know for a day. I'm open to input and direction, I have done a fair bit of research on this and seem to be reading that the resonance is usually the problem, i might be picking up an AOS/catch can in order to eliminate the stock plastic in an attempt to gain more flow, but i really need help solving this first... |

Looks like you haven't searched hard enough if you can't figure out why its running lean like that.
The answer is in the last link Psychoreo posted |

Just fyi after some simple tightening and a basic tune the Cels are gone also I have added larger injectors (wrx blues) and removed most of the restrictive after cat exhaust. Butt dyno says more top end, much more :P
