I have a 06 Silverado with a 4.3L Vortec in it. I've really been looking for some kind of tuner/programmer/chip or anything to help boost its performance. I'm not all that much into gaining HP, I just mainly want better gas mileage.
So does anyone have any recommendations for products to try? I know there are all kinds of tuners and programmers out there but its hard to find em for a V6 truck. I've heard people say to get the software changed on it but I don't know much about that so if anybody could help me out there I'd appreciate it.
And one more. thinking of getting a soft tonneau cover for my '06 Silverado short box like in this page https://truckpowerup.com/best-tonnea...for-silverado/, anybody has any info or experience with these. I'm kinda thinking about the extang fulltilt because you can either roll it up or tilt the whole thing up like a hard tonneau.
Thanks for any input
