Throttle bodys are the same.
You only see results with a larger throttle body on head & cam or stroker engine.
I have tested this on a dyno and I did lose 4 HP but I also changed my plugs to Bosch +4's at the same time. I am not sure which to blame it on because when I put the stock throttle body back on I did not get the HP back.
I am going to try a different set of plugs and see what happens.
