i have a MBC and i do get boost, but the stock gauge is reading extremely in the vacuum side. my car is running like crap, bogging down under acceleration and missing at idle and cruising. i installed a knock sensor led yesterday and it stays on from the time i crank the car to the time i shut it down. i had the CEL scanned and the knock sensor bank 1 came up, along with the MAP sensor, which is brand new from mitsu., the IAT, and the MAF (both of which should be controlled by the GM MAF translator). my guess is that the car is running shitty because the knock sensor is causing the car to retard timing. if i am correct, does this mean the knock sensor is bad?

Because it's not doing it's job & retarding Timing when it needs to - They "scream" right before they blow up!
