FYI GS400 ECU learns and compensates you may be lean
Guys I though those of you that are boosted may be interested in this.
It seems that the Gs400 ECU will compensate for tuning done by the SAFC. It appears to be about 150-200 miles once you hit this level the car starts to lean out the AF mix. I'm not sure if it does it for other Piggy backs and it may only be an issue once you get over a certain boost level.
But I thought it was worth mentioning because if you dont have a wideband installed in teh car you may be driving around thinking you have a good AF mix but you are actually lean.
