GO
-Nelson tune or Superchips Flashpaq
-Headers
-Cold Air Kit
-Vortec Fire Power Ignition Kit (Performancedistributors.com)
-Nitrous 100 shot
-Underdrive Pulleys
-MAF sensor

Show
-DJM Susp 2-4 drop
-Tint Windows
-Wheels and tires(want black whells on green truck, look good??)
-clear headlights

All input appreciated........Dont be scared to tell me something is junk.

 

i say no to the maf sensor..absolute waste of money..add 4.10 gears and detroit trutrac and 3000 stall to your list..maybe some ported heads and if you have the 906 heads leave the 1.94 valves in them..dont go to 2.02 valves in those heads

 

kk. what bout the nitrous and all that would it be safe for almost 202000 miles?
