When you changed you pulleys did you retune? I'm adding 1.5 additional PSI should i have to reflash my pcm?

 

I never did from 7-10 psi. I bet you will be ok.

 

I would recommend a retune. Would really be in your best interest to get it dyno tuned
or street tuned and get away from a mail order tune. Adding boost could cause you to go lean and with forced induction that means BOOM!!!! Just not a chance I would be willing to take myself.

 

yeah I want to dyno tune but I want to wait until I get heads and cam to do it just one time instead of paying twice for the same thing?
