ok guys so i had been using a stock (scaled to use hertz) MAF scaling in my car even though i have HKS 272's and a WR8 turbo now i have an Injen intake pipe (w/K&N filter (AMS type) and was simply wondering this which one of these parts has the most effect on the fuel trims and accordingly the MAF scaling. i still have yet to scale it, since the weather is so *** backwards nowadays it was 50* the other day then 16* and snowing (long island NY), so i didnt really think it was prime time for tuning, the car hasnt been being driven so its not bothering me but my new years resolution (part of it) was to be done with the evo (power goal wise) by the end of 2009 (seems like a long way but its better to start early)
anyway any advice would be great

 

any help with this would be appreciated, a years worth of tinkering and i still dont think i have it...is anyone running a similar setup?

 

i dont understand what the issue is...

are you having trouble with fuel trims?

 

yes...my scalings dont seem to be accurate no matter how much i log them, ive tryed searching for any posted Maf scaling tables scaled for an injen intake and an HKS 272 in/ex combo
