  1. you can bring your switch points down,or get a wideband and run open loop.I tune my 03 Tahoe in open loop SD (speed density)

    During a steady state cruise and flat terrain I have it at a 15.5:1on the highway

    My mileage increased to 19mph from 16.5 at a steady 75-80MPH

    When I get to inclines and more load is on the motor,I have it where the air fuel richens to a 14.7:1 until the terrain gets flat again.This works great

    You can also mess with your DFCO (deceleration fuel cutoff) some.Just be careful and do not overshoot

    hope this helps some

  2. ALWAYS get hardened pushrods,cheap insurance

    when you are spinning 6200-6400 RPM GET PUSHRODS

    If you don't you are crazy as they are only about 120.00 dollars

    I promise you will be happy you did

    In my opinion it is a must,just like upgrading valve springs are a must

    Always Do it right the first time
