What are your emissions numbers?

I put the Howell injection on my 84 258 last June and just had the emissions tested today. The engine has 107,000 miles.

Idle 719RPM CO2 14.9%, O2 .05%, HC PPM 130, CO .127%
2500RPM CO2 14.73%, O2 .26%, HC PPM 47, CO .222%

I'm stoked, no emissions issues with a 29 year old jeep.
