will i be able to run a slightly smaller pulley or do i still run the risk of maxing out the injectors?

 

i wouldnt run anything smaller than a 2.85 without a custom tune. many will argue, however with a custom tune for the stage 2 injectors you can drop to a 2.7, of coarse to be succesful with it the tuner needs to be good.

 

cooling gives you a denser charge requiring MORE fuel....
