ok well right after i installed my smaller pulley i did the boost bypass mod, well i was just wondering now....would you say that you run better/more power with the mod or with out the mod? never really thought about it and was wondering if any one had some insite on this question.

 

well without tuning the computer will bleed of boost to 12.5 psi... so if you don't do it u won't see the full gain

 

so if i get it tuned i should plug it back in?

 

With a hp tune you can disable it completly, like i did mine.
