Iv recently installed the rpw stage 2 cam in my car and i noticed that when the car warms up sometimes it tends to drop really low in rpms.... Almost stalling then it shoots back up to 1000-1500 and repeats this cycle until it eventually just shuts off... What could be the readon and how could i fix it?

 

any codes?

probably needs a tune...

 

The only code is a p0141 ..... I got the hackish basetune but my mechanic says it needs to be fine tuned

 

yeah, that's likely, if you bought the tune, you should have the software as well.
