According to UPS, I will get my VCM tomorrow, so I figure now would be a good time to ask the guys who have already "been there."
I have an '06 HHR with the 2.4 LE5 and auto trans. The only mechanical mod that I have done so far is a K&N cold air intake.
I am wondering if anybody has any advice as to a good place to start as far as tweaks and settings for better performance? I would like to optimize for the K&N and make the annoying "lean condition" trouble light/trac control light go away, but I would also like to improve overall performance.
I know that tuning is a learning process, but I would definately appreciate anybody's advice as to where to start basde on their own trial and error.
Thanks!
