It's not a Speedvision Hybrid is it? If so it may be normal for it to boost so late, they're quite laggy for a CT9 from my experience. I'd rather have a stock CT9!
Billy, I am pretty sure the 3 spoke isn't interchangeable with the 4 spoke. That applies to the Glanza too. Someone else may confirm. Liam I've Whatsapp'd you.
My GT was still running a CT9, I've just sold it today though. I highly doubt the new owner will be changing the turbo. I've a Black Glanza too that is going back to a CT9 set up. So that's two here.
