Gen. 1 B58 flashed back to stock with TU pump
Hey all, needing to pass emissions and have to flash back to stock. Can I safely leave the TU pump in on a absolutely stock tune?

Why not? On a stock tune, you'll be opening the Jets on the injector in stock configuration which the pump can easily handle. I wouldn't worry... It's when you need more fuel under tuned conditions where an issue occurs if enough fuel isn't provided.
What's the worst that happens? You fail inspection? Good Luck |

I'm a lil late but yeah, you should be fine, just make sure to set it to the TU pump in your options for the HPFP on the stock tune otherwise your car might not start.
