EVRY mod ++

So the EVRY mod, ( potentiometer between a couple pins on the fuel pump harness tricks ecu to thinking its cooler than what it is = more fuel = more power) Controlled by an on off switch... But got me thinking more fuel... All well and good, but would be better with more boost.

Now I know you can get a smidge more boost out of the 1.9 tdi pre pd engines with a mbc before limp mode kicks in. But I'm wondering if anyone's tried upping the boost with the evry mod running. If you can achieve higher boost without limp mode with evry mod running, you could fit a 3mm solenoid valve (connect to the same on off switch as the evry mod) so the valve would open when you flick the switch, allowing the mbc to be "engaged" and when the switch is off, it closes the solenoid valve resulting in standard boost.

Thoughts?
