Is the chargepipe something that needs upgraded as soon as the JB4 or if I keep it to map 1 (12.5 psi?)do I even need to upgrade?
The charge pipe can fail on stock boost so adding a charge pipe should be at the top of the modding list. Definitely a must do if doing a tune and pushing boost. Not something you have to do instantly but it should be in the plans to do soon. ER is a great quality and fitting charge pipe if you are looking for a brand recommendation.

Mike,

Thanks for the recommendation. Can you explain to me the need for the 0,1 or 2 methanol bungs? I don't plan on ever doing methanol so I imagine I don't need any bungs on the pipe?

No you wouldn't but I always recommend one just in case and for re-sale value. The bung comes capped so its like its not there. You just never know. The bung is only a few bux so its good insurance incase you need it or when you go to sell and your buyers wants a bung.
