So you're driving it untuned (or on a basemap) on stock injectors?

Yes, you need larger injectors before you tune...there is no point in going unless you have larer than stock fuel injectors. Do you know which size injectors the basemap is for? Chance are, its not for stock ones which is why your car runs like crap
