Default Odd problems after stage 2 on 08 sti

So I got my ap today and flashed the car to the stage 2 93 oct map v.300. After following all directions I went to start the car and had a problem doing so; it took forever to turn over. After it started I put it in gear and began to drive away. It stalled out when I tried to take off from a stop sign. The car also feels less powerful after the flash. It has given me problems started and stalling several times tonight (but not every time). Any ideas? I am going to data log (what should I look for?) and then revert back to stock flash.

Looks like I'm hitting the target boost and it is running much better today. Anyone can tell me what I should log?

The AccessPORT has a default set of logging parameters. I would start there.

When you reflash a map, reset the ECU, or disconnect the battery, all the ECU's learned values are cleared. This can make the car's performance feel a little "soft" until learning commences. There are even learned idle parameters that could potentially prevent stalling issues once learned (and the issues return when those values are cleared). I would try to diagnose the stalling issue - it may be a mechanical problem. Try taking a peek at the A/F Learning #1 A, B, C, D values (you don't have to log them) and report back the values.

I am not sure what happened but the stalling has not happened since. I also am thinking the perception of power loss is due to the smoothness of the tune. I was probably getting boost spikes before. Car seems to be running like a champ now
