Thanks so much WAfatboy. You and people like you are the reason forums are indispensable for owners looking to avoid wasting time, money and tears if they're not the "pioneering" type.
Your reports have made my decision to just upgrade my Termi slips with the Termi header. I can get those for around $1,500 or so, they're quieter (the slips are loud enough for me) and I probably can get away with just the up-map that comes with them instead of hours and hours tuning and aftermarket fuel controller stuff to compromise my remaining 22 months of warranty.
