You will gain some power from them, but if I remember correctly, the UR set doesn't incorporate a harmonic balancer, which can upset things? (someone verify this?) I have the AEM set, and they are OK, but didn't yield that much power. My lights dim and my fan blows slower at idle, but at speed it is fine.

Do you have I/H/E yet? I'd do that first.
