buy aftermarket ecu but pre-tuned price also almost the same as buy second hand standalone.
aftermarket ecu also need re-tune, as standalone also need re-tune. why only standalone need to standby money? care to explain nappx?
now stock ecu can be tuned without the need of chipping or after market add-ons management...
no modifying.. thus no messy wiring issues... 100% stock.. ppl wont...
