Thanks for keeping us updated on the issues you were having. Most stated what I was thinking could be the culprit as I am running into simliar but not same issues. GLad to hear you got it fixed!

 

I used to have similar problems with my emanage ultimate. The car would run awesome one day and then randomly it would run like a pos. When doing a pull the exhaust note was different when the car did this. On mine I think the piggy back and the stock ecu were fighting each other on the timing. I eventually just got a AEM and called it a day, never had that problem again.

 

Get rid of the piggyback.

 

Meh, I love it and I can pass inspections with flying colors.

 

Get the new Kpro, little bit of work for a huge amount of benefit

 

I still have my emanage, just for smog purposes. I install it every year for emissions and then remove it after passing.
