Those who said to use K3VE-T are really newbies! Do u know how much is the halfcut alone? Plus, the stock turbo is small n running on OEM ECU.
This fella using a bigger turbo + standalone management. The ECU itself costs RM 6k and it is highly tuneable. Try to tune the OEM ECU... see how much money u need to spend. Putting SAFC or RSM are nothing compared to Haltech E6X... those are merely 'rice' toys.
Anyway, congrats on the successful BOT.
