The SUB-003 is only available as a single type of AccessPORT, the v2b. There may be some early v2 AccessPORTs out there still, but either one will work exactly the same way on your car. The only difference is the style of tuning cable that is used, but again this will not affect operation in any way at all. I believe someone said something about a v3 AccessPORT? This does not exist. We only have the one style of AccessPORT available.
As far as the mapping goes, the stage1 map for your car for 93 octane will be the one you want to use. As you noted, some users do experience boost control issues, but this is generally due to some other factor, a bone stock car should not overboost. However, these cars are notorious for having some boost control issues, but this normally only happens on modified vehicles with catless exhausts and intakes.
If boost control is a concern, we do offer LWG versions of our maps. This will limit boost in the mid-range where overboosting is common. They are basically just less aggressive versions of the normal or HWG maps.
Should you have any issues with your AccessPORT or the mapping, please do not hesitate to call us at 1-866-922-3059 and we are more than happy to assist you with any issues you may have. Enjoy your AccessPORT!
