Hi all...are going to look at a 2016 STI... a possible purchase that has been mapped,not too many details apart from it has miltek exhaust and apparently pushing 360bhp,what's a SAFE LIMIT without forged work?.
any input would be appreciated.

 

I doubt it's 360bhp firstly with just an exhaust an map. But if it is, providing the map is safe and the boost is below 1.35ish it should be ok, but nothing is guaranteed with the 2.5

 

from what i've seen the milltek exhaust is very good on the 08+ so 360 on good fuel wouldn't surprise me (assuming it a full decat and a flat out map). I'd agree about 1.3/1.35 bar is as much as you'd want to push it but at the end of the day it's a 2.5 it's going to pop if it's not been fixed yet so might as well start saving for that now and enjoy the car in the meantime.

 

The 2014+ models perform realy well. We often get results of 360-370 from these cars. Wen also stay below 1.4 Bar boost and conservative timing to keep the HG and pistons alive...
