Rather than start a whole new thread I’ll revive this 5 year old one...

wondering if anyone has played with this in the last 5 years with any real results?

I had a focus ST and doing this “mod” was very common on them. It would hold another 2psi or so, throughout the rpm range which really helped the car pull. All I did was tell Torrie at unleashed I did it sent him one datalog and he made whatever changes were required and it ran fine.

wondering why we don’t do it on these because I watch my truck Peak say at 21 and then only able to hold 14-15 through the rpm range. Even the ability to hold 16-17 I’m sure would be beneficial and still not to much where you’d be turning the turbos into heat pumps, am I wrong?
