If your willing to travel to dubuque which is not far from madison we have powrtuner and hptuner with widebands to tune but i just sold my pulley puller so we may have to arrange to borrow one from someone else if needed. The one who does the tuning is "Gooch" on here. He has run a pb of 12.3 with cam and genV, he is pretty good at this.

You wont need to weld a new bung for the wideband, and you'll have to ask him if he has the 03's unlocked for hptuners to figure out the cost.
