was robby woods driving?
Just got back from Cali on a turn around trip with the Chevy Colorado Ecotec Unlimited Lites #13.
Are you running a 2.4L or 2.2L and is it modified?
Actually it's a combination of both not molested.
We are getting closer and closer with cam changes, intake changes and so forth everyone else has turned in other directions but Chis at CBM is determined with the Ecotec program. Mostly for reliability reasons I think.
