I dynoed one at 10hp and 12torq, but I think that It was just the a better pull on the dyno. I had a lot of trouble with LPF (Lightning Force Performance) TP, I returned it. I went back to the stock TB, until the BBK came out. Since then I have been using the BBK. I haven't had a chance to dyno this one. Unless you plan on FI or getting improved heads and cams.(I plan on S/C in the future). You better off spending the money elsewhere. Even though MM&FF test the throttle body and gained a lot of power, but then agian that is a magazine test. I haven't had any problems at all with the BBK unit, lots of people have problems with the aftermarket TB's. Such as erratic idle and failsafe mode, but I would have to say that the throttle response is better than better(same tune). SOTP feeling is barely there, if you are set on getting a TB. Then get the BBK it is the best among the aftermarket throttle bodies.
