I own an 01 gmc sierra with a 5.3 and a 4l60e behind it. Im still somewhat a newbie when it comes to adding performance to my truck, so I was wondering what I should do next. I just added the new intake,flowmaster 40 series, and my vette servo is on its way. What should I consider next

 

A PCM tune from one of the sponsors to the right. Blackbear, wheately, nelson...

 

Will I have to get another one eventually if I put a cam and new heads or even a shift kit in it?

 

Ya if u get a tune now u will need a retune after h/c

 

So should I get the blackbear tune now, then get my shift kit 4.11s and h/c or should I wait till I at least get the shift kit and gears. Also is that the best gears for highway and torque?
