I just purchased an 09 Wrx 265 and was looking to upgrade it a little. I have an Accessport on order from Perrin which will include a custom Perrin map. There is a down pipe and exhaust mod to the car already (Not sure exactly what it is). And i plan on getting a cold air intake (maybe Perrin). I know that certain mods may cause the car to run lean due to the MAF sensor, So if i have a custom tuned map will it ensure that the car doesn't run lean?
