^ hiboost can and it'll cost you out the ass. Lowest i've seen an EMS for a KA is i think $600 or $700

Why not go for a hacked oem ecu w/good tuning software to tune w/ I.E-Nistune,Calumsult(Hard to find now and no longer make them),TunerproRT,etc and have martin tune it. Prolly save you half of the AEM route after you buy the unit and pay for dyno/tune and it will be essentially the same as standalone.
