I have 2004 Sliverado SS AWD and I am wanting to get my truck tuned. I was probably going to invest into the F.A.S.T. system( http://www.fuelairspark.com ) and I was curios as to if it is worth the money or should I just get it tuned by a tuner?

 

i guess our answers werent good enough for you on sss.com, a fast is slower than our computers. get it tuned by someone or learn to do it yourself.

 

No thats not it. I am just tryin to get as many opinions as possible. I wasn't getting very much response on SSS.com so I tried this forum. Nothing personal.

So the FAST system is slower than our present pcm. That is very interesting. I did not know that. I think I am leaning in the way of Zippy Tune.

by the way nice truck!

 

in my opinion the stock computer would do you just fine..it would be alot cheeper getting efi live the all the fast set up..if your makin 1000 plus hp now it may be a different story

 

very true.

 

you guys have all brought up very valid points. It looks like Zippy for me.
