Definitely.

Or get a larger pulley.
 


if you get a 4.0 pulley youll be safe until you get a tune. you should be monitoring your knock too. you definitely need to tune it though. stay off the throttle until you do.
 
asking for alot of trouble here... I wouldnt worry about getting it tuned as much as I would worry about getting some boost taken out of it... or something like an intercooler or headers installed.
 
you need supporting mods.
get that stock crap off.
get headers ASAP, get an intake on that thing ASAP, get some cooler plugs ASAP and tune it ASAP.
