Seriously though, I wasn't exactly trying to be a dick, but you did make this thread basically asking why you can't do a brake stand. Also those two mods are going to do very little for your power or fuel economy. Handheld programmers are nothing compared to a good custom tune from a reputable company, and most times they're actually more expensive. The throttle blade mod is good for increased throttle response with less pedal travel, but it's not going to give you any extra HP or torque whatsoever. I have it done in my red truck. There's a lot better ways to spend your time and money. My suggestion would be to go through everything and do a full tune-up. This will undoubtedly provide better power gains than what you're talking about doing. My Suburban is bone stock and will roast the tires from a dead stop, no brake torture necessary.
EDIT - Just realized that you've got a 3/4 ton, should have read the original post closer. Comparing our 'burbs isn't really valid due to the weight difference. Still though, don't waste your money on a handheld programmer and don't expect any real gains out of the throttle blade. Once you have everything tuned up I'd recommend a tune from Black Bear Performance. Best thing I ever did to my truck.
