TPIS cannot say that their non emissions legal cam will pass emissions even if it will, for fear that one of their people saying so is misconstrued as saying that it's legal...

 

I have thought about sending them my pcm but they charge 575. to program it plus down time when I send it to them. But I have found programing for less and so I went that route but I do know TPIS is very good at what they do. I am just trying to save money. Of course it may cause me to spend more money in the long run.

 

My TPIS Stage V chip had way too much fuel and too little timing. I have tuned it myself and it runs great.
