I have the Stage 2 kit, but have not had it installed yet. The Stage 2 installation includes a PCU reflash for the injector injector. If I go with a smaller pulley than the one in the Stage 2 kit will I need to reflash again because of the gain in boost or is the reflash just because of the change in fuel pressure?

 

no just slap a 2.9 on their and go.......no tune needed unless u get biger injectors etc....

 

stage 2 + 2.9 =

 

The smallest pulley your going to be able to run on 42s is a 2.9". A dealer reflash wont make you anymore power.

 

If I have the Stage 2 kit installed then swap the stage 2 pulley with an even smaller pulley will I have to reflash again? Would I benefit in horsepower by going with an even smaller pulley? And what is the smallest pulley available which I would benefit from while keeping the Stage 2 42lb injectors?

 

haha 95cam86roc just told u........no u dont have to get another reflash, 2.9 is the smallest u can run on 42lbs SAFELY!!!!. You would benefit by going with an even smaller pully IF you got bigger injectors which would make buying stage 2 pointless. you have stage 2, now all u have to do is put a 2.9 on and thats it nothing else

 

Personally.... which this is what i did... I would have just bought some 42s, a 2.9" pulley, stg 2 belt and got a custom tune via HPTuners. 1) Overall it would have been cheaper 2) You would have made more power this way and 3) You would have had a better tune

 

the stg2 pulley is pushing it, i say go 2.8 and 60's

 

A 2.9 on 42s is fine plus he already has his stage 2 kit.
