With my truck, changing from the batmo s475/83/.90 to the HTT s482/87/.90 with a 1055, spooling on the line became impossible (just above sea level). With the s475, boost would come up quickly beginning at 850 degrees, 2300 rpm. With the s482, i was limited by the converter and while spooling on the line, my logs would flatline at 2350 rpms and 4psi of boost, 1000 degrees. I switched to the DPC custom converter for Denver and could build 1200 degrees, 2600 rpm, and was launching at 12-16 psi. I broke the crank, rebuilt the motor with DTS heads and cam, more compression (more protrusion and tighter piston to valve) and with some more time spent tuning it, could get it to light faster than ever. However, it still needed 1100 degrees and 2500 rpm to begin to light. Currently, my converter is stalled at 3300 rpm and drives and tows as well or better than the 1055 did. It locks consistently even with bens box turned off. I have gone through similar trial and error to Camomax, who had to make similar changes to his setup when he switched from the s475 to the 82 and he was running the 83 turbine with a loose housing
