im looking at a chip instead of a tuner for my 2000 5.4 until I get the money for a tuner. anyone have opinions on Peak Performance brand? promises 150 hp and up to 30 mpg which I doubt that. but any input would be helpful

 

Do not waste your money on that. Save it for a real tuner.
If it was that simple to add 150 horses and get 30 mpg , everyone would have done it by now.

 

Rip off. Does nothing good.

 

Total junk. The venders should be jailed for making those outrageous claims.

thought id ask. thanks guys

 

I bought a used superchips programmer from a member of this site and I'm very happy with it.

 

I still haven't quite figured everything out on this site yet. im kinda behind with the computer for my age.

 

I have seen good results from SCT xcal II and edge programmers in our trucks.
