Wondering what you all think would be a good tune for my gas hog. Not looking to brake the bank here. Tell me what you know about what the gains may be, thanks in advance.

I have a Hypertech in an 8.1 Suburban, it works nice but mine was used. I bought for $150 and it doesn't change speedometer calibration for tire size. I also have a Superchips in an 8.1 Avalanche, it was $350 new, I like it better.
