Default Accessport stage 2 slower than stock

So I've been running stage 2 on an accessport V2 now for about 1200 miles and kicked it tonight in a spot where I normally can reach pretty much max on the motor. I did the same pull with both my full catless exhaust and k&n filter before installing the accessport and ran 25 miles an hour faster than with the accessport. I'm not talking 1/4 mile I'm talking mile and a half of straight and flat. Also the car is wideband and before the off the shelf map at WOT it ran 11.1 to 10.7 now it runs 10.0 and I presume below but that's as low as the wideband goes. Do I need a protune? Any advice?

Best thing to do would be to get a 3rd gear data log as described in the video below (if you can do so safely). You can post it up on goggle docs and we can take a look at it (make sure to set the permissions to public).

Heres the public file with a third gear pull. I was reading 10.0 on the AEM UEGO thats only 3 months old and the COMM FUEL FINAL was reading as low as 9.2 at one point on a previous pull I did this morning.

How much driving have you've done since you've installed the AccessPORT or reflash a map?

Your dynamic advance multiplier (DAM) is sitting at 0.75, which means that the ECU is only using 75% of the dynamic advance ignition timing map (which is added to your primary ignition to determine the bulk of the final ignition advance). So, basically, you are running less than ideal ignition timing. The DAM should normally move up to 1.0, but it is a little slow in some of our 06-07 WRX maps. We are going to work on fixing this in the future. For now, you have two options to help it along:

1. Try hitting moderate, steady boost from around 2000-3000 RPM.

2. With the free AccessTUNER Race software (for v2 users), you can make a change to your map (if you feel comfortable doing so) to increase the learning response of the DAM. You can request a free copy of the software here:
http://www.cobbtuning.com/accesstune...st-s/70716.htm

The procedure to make the change would be as follows:
Your DAM has reset to the initial value because you've reflashed a map. If you want it to learn faster and feel comfortable using AccessTUNER Race, do the following:
1. Open your map in ATR
2. Under Ignition Tables -> Knock Control group, select the "Coarse Knock Learning (DAM) Mode Min. Dyn. Adv. Map Value". Current value should be 4.0.
3. Change this to 2.0.
4. Save map with a unique name
5. Transfer new map to AccessPORT with AccessPORT Manager software.
6. Reflash (not realtime) the map to your car. For this car, this will require you to connect the green test mode connectors (and disconnect after reflashing).
