    Help with MAF Scaling Turbo XS

    Hey guys,

    I need some help with scaling my MAF. I bought an 07 WRX a few weeks ago, and it has a Turbo XS short ram intake (link here) and had no tune on it what so ever. Are there any safe values I can apply to it to ensure I don't lean out / knock? So far I have applied a 'safe' stage 1 91 octane tune (link here). Runs much smoother, but I know it won't help the scaling problem.

    Are there some table values I could copy over from another tune which are better?

    Until I get the scaling fixed, i'm going to try running 94 octane at my next fillup.

    Going to log a half hour cruise with easy throttle changes, and hopefully some 3rd gear WOT runs asap. Will post them as soon as I have them.

    Unless you can find a MAF scale for that particular intake then no,there are no values you can just plug-in. The links above explain how to scale the MAF. You also have the option of purchasing a map from a tuner that can customize the map for your car. They can do this remotely.
