That was TST on 4/4 and EZ on 4. Besides the boxes, I have a Scotty III, and nothing else in the way of performance mods. Unfortunately, I didn't get very good numbers, because the TST's EGT-limited defueling kept kicking in and cutting off the upper end--even when I bumped it all the way up to 1550. Basically, the numbers came out no better than the EZ alone (which doesn't smoke, except at high altitude and high load). Therefore, before finding a better air solution (turbo(s)?), the only advantage the TST seems to have over the EZ alone is selectable smoke (and lower rail pressure if run alone).
