| You might get away with it for a while, but you WILL run lean at some point and blow your engine. How do I know? I did it. I put in 14psi boost jets at Stage II. That was a big factor in how quickly I got to stage VII (and spent over $15k in a VERY short amount of time). If you don't have that much money to blow, I suggest you not mess with running boost jets with no ECU. I wish I'd have listened.
