I need a little tuning advice.  I have a 91 GMC Sierra with a TBI 350.  I have gone through the engine and put a Crane Computer cam in it along with a set of vortec heads, GM Performance Parts intake and a set of intermediate headers.  It runs pretty good now but it has some drivability issues below 2500 RPMs.  I am looking into reprogramming the eprom.  I am just not sure on where to start.
