I have an '07 WRX and am mainly interested in deleting trouble codes associated with the secondary air injection system. Mine has failed some time ago and I will be deleting the system soon. I am very mechanical but am inexperienced with any kind of electronic tuning.
I am planning to buy the Tactrix 2.0 and am curious if it is better to use their ECUFlash software or to use RomRaider? Again, I am mainly interested in Deleting the DTCs. I will eventually do some very basic tuning as I will do some minor upgrades to some of the hard parts, but will likely use off-the-shelf type maps...and possibly buy the Cobb v3 down the road (when I can afford it).
Thank you for your time.
