My point was, in the box all i had was a single piece of paper with the liability and legal disclaimer. No instructions, nothing else. But, based on the images above, i installed it right.

I did get the check engine light. code P0171, Too Lean. Although it runs great, the racing chip is finally being utilized properly, amazing power... the engine studders a little when its cold, when i go for a long drive, the check engine light goes off, but soon as the engine is cooled off and started again cold, light comes back on pretty much right away.

Any suggestions? Maybe need different MAF sensors?
