The EP3 was left parked outdoors for a week, and now it's not spooling any boost! Car drives "normally", no lights, just gutless and I get lean cutoffs because I'm running open loop and my tune was never optimized for this section of the fuel tables.

Looked under the hood and found a dead mouse by the passenger's headlight. What's the most likely damage it did? At first I thought it was the bypass valve, but now I'm not so sure. Something electrical? Bit into tube so it no longer holds pressure? Clogged intake or exhaust with droppings?

Where should I be looking?
