The current mods would require a custom tune which can be done through a protuner with the AccessPORT. If you were to swap the intake to the stock or Cobb SF intake (which our OTS maps are designed for in this case), you might be able to get by with the OTS stage 2 map, but you would have to carefully monitor boost via data logging to make sure (you can data log from the version 2 AccessPORT, assuming that is what you have). Ultimately, though, your best bet would likely be a custom tune and you will generally see some decent gains with a custom tune as it is a tune specifically tailored for your car, mods, and local fuel quality.

We do offer a $200 credit towards the purchase of a version 2 AccessPORT through us when you trade in your v1 AccessPORT:
http://www.cobbtuning.com/AccessPort...in-s/70459.htm

In addition to the data logging feature, this would give you live monitoring from a selection of numerous engine parameters, launch control and flat-foot shift, free AccessTUNER Race software, road dyno and performance measurements, possibly of speed density tunes and more. The version 2 AccessPORT would also be a better choice if you are getting a custom tune.

If you wish to keep the v1 AccessPORT, then your other option would be to get a compatible cable to use with open source logger such as RomRaider.
