I did my first datalogs today and I am concerned that I am running too rich. At cruise, I am at around 14 AFR average at cruise. I'm wondering if it would help to run the stage 2 map with my mods. Currently running the Stage 1+ MSCAI 91 v107 with the following mods.

MSCAI2, MSCBE, Test pipe, TIP

Any input would be very appreciated. I want to make sure that I'm running the car safely until I can protune.
 
14 what? 14.0 or 14.69? If it's 14.69, you're good. 14.0's, there's something wrong.

It would be nice if you could post the datalog here, one cruising for about 2min and then a WOT log, from 2.6k to 6.2k rpm.

Log: Accel pedal pos, KR, AFR, LTFT, Maf volt, Maf Airflow, Boost, Di pressure, Throttle Position, Calc. load, Boost Temp, Spark Adv, WG duty

Its right around 14.7- 14.8 I will try to post my logs. Whats the best way to post them? I have Open Office and tried once to attach a file unsuccessfully.

honestly search around a bit, for emission and other reasons afrs are suppose to be at 14.7 while idling and cruising.
 
14.7 is normal for cruising.

Low 10s and 9s would be rich at WOT, but its not too much to be concerned about as it basically runs like that stock.

That is good to know thanks. I need to find some clearing to do some WOT logs and see where they are at. I was able to do about 3/4 throttle and the afrs were around 11-12
