I think thats what i'm going to end up doing next then guys.. is the E-fan then the pullies....

I would get a tune but i dont feel like shedding $350+ for a tune and buy a new mod a week or so later and have to get a new tune seems to much of a hassle and time to go through... When i get ready to install my ls6 heads/ Custom grind cam/ and nitrous setup then i'm going to get Nelsons custom tune..

You need a tune for the efans if you want to control them using the PCM, otherwise you have to but in a toggle switch....

I like it a lot.
Smooth power from idle up to 6200.
You might go a lot bigger with the tci 3200 right?
I just put the 4.10s and truetrac in.
Very happy with the truck right now.
Looking to build up the tranny next.

the tune is worth it. with nelson, you pay $375, then the future tunes are free. if you end up doing serious work, you only pay like $100.

if you want a noticeable mod, do the tune. nelson did mine, and i immediately got 27hp to the wheels on a BONE stock truck.

as far as bolt ons go. get the fans, they make a noticeable difference. i dont think 15hp difference but probably 5-7. plus the fuel mileage. then do a pulley. they work very well together. with fans, a pulley, an intake, those longtubes and y-pipe + a tune, you should get very close to 275-300 to the tires.
