Thread: SS M90 misfiring due to tune?

MAF table could be off by that much too.....I've seen it that way. But even with the Intense pcm, it suggests something isn't right.

Kinda off the wall, but have you checked the O2 sensors? If it's going bad, it can throw a tune off also.

Hmmmm. I'll have to look into the O2 sensors. Reptile, where is your shop?
