We're at about the same altitude. I took my 06 TBA to Edmonton to have dynoed. I want to sort the results and get them to Staffo for his chart, but this is the quick story.
I went with 155 mains, TBS needles, and 45 pilots. On the first run it was very rich across the whole range. So we changed out the TBS needles with single shimmed stocks,and reduced the mains down to 152. On the second run it was still rich midrange, so we took out the shim to run straight stock needles. This gave a good dyno run.
As a side note, I'm really surprised at the difference in milage that the stock needles are from the TBS cousins. With TBS needles I average 170 to 180 km to reserve. With the stock needles, and it doesn't seem to matter whether there is a shim or not, I average 220 to 235 to reserve.
