i saw that too and was quite impressed! A mate's MX83 with a 1jz-GTE (vvti version) and auto box ran on the dyno on the same day... he hit speed cut pretty noticably around 180kph.... both runs were in 3rd gear on the A341E's.
if you do have speed cut - i have a little circuit that can reduce it
actually it can modify any electronic speed signal by applying a ratio! Im going to chuck one on the cruise control, cos the bastard thing wont set cruise above 108kph
