Fastman modified my stock TB from 80 to 84mm. Very nice work and delivered as we agreed. The gains from a TB mod are small and won't be felt unless there is a sophisticated method to measure before and after. It's one of those every little bit helps mods.
When asked about tuning for the TB my tuner said "your tune is good for a TB mod". My question is why would recontouring and increasing TB throat required a retune? Since the engine is NA it's only going to flow what it's size and rpm require. I don't understand what tables would need to be modified for a slightly quicker transition of airflow or a slightly increased maximum airflow. Granted my tuning knowledge is minimal but I'm hoping some of the guys with greater tuning knowledge can provide some useful information.
