I have a 1997 Chevy Silverado 1500 5.7L, and I'm trying to find a way to eliminate the 100mph limiter and gain economy at highway speeds. Right now I'm interested in a hypertech max power chip. Does anyone have any experience with this product or any similar ones?

 

bump

 

I dont like programers myself if I were you id get a tune here' some links

the only thing I don't like about the idea of getting my ecm tuned is that I lose the ability to toggle between economy and performance whenever I feel like it

 

Thats cool heres another link Im not sure witch one is the best but I always here people say hyperjunk instead of hyperteck. I think that Diablo is a good one.

 

I'vehad several different people refer me to diablo, do they strictly tune ECMs or do they also make tuners

 

Sigh...follow thew yellow brick road, lol.......

We need to make the Programmer/Tune discussion a sticky!

 

ya I've had too many people tell me its not worth it to buy a power chip on a gas truck, so now I'm off to find more ways to waste money on my truck instead of my sled for a change, any suggestions

 

For your 350, I think a free-flowing exhaust, intake and TB spacer would make a difference in power.
Mabye even some headers.
