My decision to use 4 O2 sensors was based on keeping as close to GM build as possible to obtain euro 3 emissions, if it works for GM product why not stick with it, the test report consists of 2 pages first page with all the numbers the second has the graphs. I also to the car to an EPA noise test, i had done some preliminary tests and i was achieving under 90 Db on the default V8 RPM (3300) this was also the case with EPA test, however if the test is done at 75% of advertised power (6.0 is 260@5600) then the test is about 4200 rpm my test was 92 Db the EPA was 96 Db a bit disappointing but the EPA guy said if the engineer uses the default all will be OK have to wait and see next week.

When i drove it to the test it was so quite a bit like a new SS off the lot.

will try to build my gallery if i can work it out.
