If you are going to stick with the black box, contact Black Bear Performance about a tune. It does sound like the 0411 swap would be beneficial with what you are doing though (now and in the future).

Thanks, we already got a pcmforless tuned blackbox and runs very good!
of course maybe there is more to do IE a Dyno Tune but that will be next.
