• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Would this be safe to do?

Just got my Overkill tune in the mail today. I have Speed Daddys and a 3.4 pulley to put on too but I'm gonna be working 60-80 hours all December so I'm not gonna have time to put the headers and pulley on until atleast January. Would it be safe to go ahead and put my Overkill PCM on without the rest of the parts or should I definitely wait?
 


Assuming your only missing headers and the pulley you should be fine. Stock pulley and manifolds shouldnt cause any issues on his tune. Now if you run the 3.4 and no headers.... bye bye engine.

There is no benefit to installing a pcm tuned for better flow and higher boost without them being present.
You'll just waste gas.
 


If you put it in, you'll gain a better performing trans, but the timing and fueling will all be for the higher boost associated with the 3.4 pulley. I would wait.
