Default New dump valve, eml sport and cruise light on

Hi lads

came here for some advice as me knowledge of engines aint up to standard yet!

got a new dump valve fitted on my 09 STI. Drove fine for a couple days then the eml and traction light came on and sport and cruise light was flashing.

Car was previously mapped by previous owner at andrew carr so wanted to know of the ECU needs tweaking again to accomodate the new DV? Which is a HKS SQV. I thought it didnt need one but diagnostics sayings its running lean.

checked hose and everything is snug and secured, no visible gaps anywhere

I know some ppl have theres run ****e with a new DV and go back to recirc but my chavvy self loves the whoosh 🤷🏻*♂️

Any suggestions would be great

TIA
