It is less hassle to tune for the efans so I would do those after the tune. TB spacers are worthless and don't do anything on these engines. Depending on what gears you have, get you some gears and a locker. Of course you will have to get the tune calibrated for those...

yeah, i knde know about the spacers, i just like the way they sound, lol.... my truck has 22's, and somebody on the forums told me that it came with a 3.73, you think i should get more gear??? im going to make the drive to nelson in about trhee weeks, and get them to install my ls1 e fans, you think that will be good enough??

22s you might want some 4.10 gears!! It should be running good. Make sure he does a street tune!!

this is what the truck will have before i make the drive to san antonio:
