The new filter will give a good airflow improvement, I'd not go mad with the TB to be honest as intake restriction isn't the TB. The work done to the TB so far looks good but I don't really think knife edging the butterfly will make any difference to power production as the intake losses are elsewhere inside the plenum. The I ran a back to back test using the standard 180 TB then switched to the larger 190 TB. I was surprised to see no power gain at all. The KV6 is cammed with a really short duration which really hampers it's power production anyway.
