hello! new to this forum. i just picked up a s15 spec r with 100k kms imported from japan to ontario canada.

I understand i probably need to tune the car to make up the difference of air/fuel. so the car already has a nismo catback exhaust and an intake. i'm thinking of doing intercooler and a downpipe before bringing it to a tuner!

now to tune the car do i need to update the ecu? i'm trying to do research but can't find much on this topic. it seems like i need to get a standalone just to do a simple dyno tune.
