Boost leak??

[nick92S2]

Home fried 92 3B - Help needed.

My car struggles to reach 5000 rpm, and I can hear a huge air leak especially when changing gear - I presume this is a boost leak. Anyone got any advice on where to start? Pictures would be good if poss, cos I’m no expert. I fitted a boost gauge 6 months ago which used to reach 1.5 bar now struggles to reach 1 bar.

I have been messing with the diff lock tubing under the rear seat - could this be connected???

Thanks

Anees - yeah it does sound like a dump valve. Which hose was split on yours?
