I agree. I took them off last night and started reassembling the stock IM/TB. I’m going to tune it that way and hunt down another sensor and fill in the bypass holes. Switching back and forth is pretty easy. I need it running now, I need to get racing… I haven’t given up, and these will be worked out.
