oh ok kool... yeah well ive already got the ECU, because when i got the neptune, that came with another chipped ECU, so i can have my P72 sent away for chipping, so for the s300 im looking at 800, + the chipping? why isnt the bloody chipping included in the 800? but i think because my ECU is JDM, i need the S300J chip. Do i need to buy the boost solenoid aswell?
