I have a heavily modded Classic with 2.2l engine, hybrid turbo etc, when I bought the car I could have sworn the fuel pressure was set @ 4 bar at idle, now it looks like 3.5 bar, it has an adjustable FPR so I could turn it back up again, this coupled with a bit of Cocklink activity has gone me thinking about uppng the pressure what do you guys think?

 

4bar fuel pressure should be stated with the vac line off.. therefore static.

3.5bar with vac line on is about 4bar with vac line off..

I think you posted another there about knocklink activity at 7k?

thought I had then was are you sure that is not the rev limiter?
