Really? 240hp? What kind of ECU do you have? Back when the car was tuned over the summer i was not too familiar with AEM and so didn't want to tune it myself. Since then, i have done a lot of reading and research and i am def tuning it my self next time. If you wouldn't mind i'd like to take a look at the map (when it was tuned on with the GT25), to see if the tuner was way off on the ignition timing. I actually had to redo the fuel map, went to a boost compensation map, cause the way he set it up it was running way to rich, like 10.5. I got it steady at 11.6 on boost.
