there are a few people running a 2.9 with colder plugs and no other supporting mods

 

sorry lol... just wanted some feedback with ppl who have them installed to see if its really worth it

 

its worth it ..but if you are really tight for cash ..just keep it stock now and wait ..patience will get you the best deal ...

you might find that once all the stage hype calms down people want 2.8 and smaller pulleys and have their GM 3"ers for sale for Cheap ...

 

true very true.... i just want to go faster lol

 

then you have to spend $$$

pulley is your best bet and hacked airbox mod ...
