Hey guys! just figured its time to join since i have a 03 tahoe. i do have plans to upgrade a few things. i think my first plan of attack is to swap out the clutch fan to the eletric duals thats on the 05 and newer followed up by a tune from black bear performance that includes what you need to run the electric fans get an intake and change out muffler. eventually get some shorter gears 3.73 or if i can find 3.90 which i swore i have seen somewhere before. at some point i would like to rebuild my motor i have seen a lot of options to get some good power that don't cost a lot. oh almost forgot first thing is get the A/C fixed my compressor makes a crazy noise, still blows cold air but i know it just a matter of time.
