chips for an 03 6.0?

Superchip, Edge, Diablo or other tuner?

--------------------------------------------------------------------------------

I would like to purchase a tuner for my 2003 Yukon Denali(6.0). Can anyone comment on the best tuner for the money and is there really any mileage increase to be realized by installing one. Do the chips assume you already have a high flow air intake?

Diablo Predator! That was mychoice and I'm very pleased with it. I like the features and the ability to fine tune your vehicle with it. Also their customer service is great.

Predator is probably the best for perfect tuning but I'd go with a custom tune from justin at www.blackbearperformance.com. Guy will fine tune your truck and get ridiculous power and mileage out of it. Wait until may and I'll have a full review of a tune on my 6.0.
