?????????????????????????????????????????????????? ??????????????????????????????????

 

Headers, ASP Crank Pulley, Electric Fans, Ported Throttle Body, Plug Wires and plugs.

 

well i have headers, and plugs wires......forgot to mention....now will the other three help and how much are they.....cause i have been looking into the e-fans, and pulley(with the pulley will it not work well with my stereo), and the ported TB hows that

 

oh yeah and what are the free mods....???????

 

Free mods are the EGR mod, Throttle Body By-Pass, and Descreened MAF.

 

i heard descreening the MAF was no good, and will the other **** mess up the truck at all....

 

I would get some differant headers. All shorty headers are, are tubular manifolds. They help a little but not that much. I put up a thread awhile back and asked what headers i should get for my truck and all most everyone told me to get the TOG's. And the e-fans will help out alot. I dont think the crank pully will hurt you much if at all with your stereo.

 

slamed...with the TOGs are they full legth or no....????

 

nope. the are smog legal. trust me i looked into it. i have talked to TOG and asked a BUNCH of questions. VERY VERY nice people and very helpful. They said on their dyno they were getting (on a bone stock 4.8L) 20 to 25 more horse from their headers. the 5.3L was in the 25 to 30 horse range. the TOG's are a mid length header. he told me they have a C.A.R.B. stap.
