After some additional in car tuning we got our 93 octane pump gas normally aspirated Schwartz 730hp LS7 to pass European emissions in England. The car had to go on a chassis dyno for the drive cycle testing.
Video link to the engine dyno test of the 1st one of these we did.

Here's a pic of Don with the car, an Ultima GTR.
