Yup mine live about 2 hours .. but I do have very short tails and they do get wet at idle. I just wait to turn on my AFR meter till I`m buzzing along for a bit and figure they are dryed out, that helps otherwise they last 10 minutes, 5 minutes if i close my exhaust flaps lol

According to the receptionist, Chris is no longer there. However, I did speak to Gabriel and he said to weld in a O2 bung in my riser is only $82.00, plus return shipping. Very reasonable I think

350 Mag MPI
I just ran my stock 350 Mag MPI engines and took a video of the stock tune with the newly installed O2's at 8degree angle. This will give me a baseline for tune changes after upgrade this winter.

Cold Start was quite surprising to me also. For the most part 3 -4 K stays around 14.3 @ 170*. Good to see that WOT A/F drops to 13.2 as the regulator raises the fuel pressure as designed. Overall, I was very impressed on how stable and predictable the air / fuel was.
