New gtir/ more power!!

I couldn't say exactly as it was on the car when I bought it, at an estimate it's probably done <15k miles. Previous owner ran it at 1.3bar and I ran it at 1.5bar. It made 380bhp at 1.6bar so its not been stressed. I was told the wastegate port was opened up for less creep and some machining was done on the inlet but can't prove either of these until its off. It doesnt creep bad at all however.

I want more low end response. Ideally Im planning to get a gtx2863 in the future. Like I said, I could be interested.
