Good information. I have had a little experience which pretty well supports everything you are saying.
One change I made, for $300, did only 1 thing, it removed the knock/ping detector input. This let the ignition advance up to 50 deg.
Unless I ran two cans of octane booster on top of Premium gas, the engine would ping like mad. Note that most "Octane Boosters" are just kerosene and some detergent to clean your fuel system. I won't name the one I used, but it was made for "Off Road Use Only" and wasn't for use on cat equipped cars. The real downside was that, at that time a gallon of gas cost about $2.25.9 and the cost of a can of booster was $5.00. So 15 Gal of gas cost about $44. I got 10MPG in that truck with the computer on performance mode.
Point is, be careful what you put on/in your car, the long term cost might shock you.

That could be true....I don't know enough about all cars so I can't say for sure. Generally, though, you can flash an ECU and then pull it it right off w/o anyone knowing it was ever there. Before doing so, I would consult with a qualified tuner who knows the platform.

That is what you call, getting carried away. Generally speaking it is a pretty bad idea to remove a knock detector....they are there for a reason.
 
Octane boosters are all the same. Actually, there are two types. One that works and one that does not. The cheap crap is nothing more then cleaners and essentially alcohol. You get a small amount of octane increase....usually something like 0.1 to 0.2 octane points.
 
The good stuff has MMT. There is no other way to do it. I have a sneaky suspicion that I know what you used - lol - and it has a lot of MMT in it, though, they won't tell you and it is not listed on the MSDS.
 
MMT works VERY well. BUT, it will wreck your O2 sensors and it coats the spark plugs. It is unlcear if the reddish dirt that forms on the plugs hampers performance, but it makes reading the plugs impossible which sucks if you are racing.
 
I always keep a bottle of it in my trunk and use it if I have no other choice. My car was tuned for 93 Octane. It runs fine on 92, but if I am stuck with 91, a half bottle goes in the tank. I am going to get a 91 Octane tune this spring to suppliment the 93 to avoid these situations. I also have an 89 octane tune. I would never use 89, but most of time, I drive with this tune. It keeps the cyclinders running a bit cooler and is less harsh on the car. I really don't notice the 30 hp loss certainly for normal driving.
 
What REALLY aggrevates me, is when people make rediculous comments about the amount of HP some cheap, bolt-on mod will make. I hate to stereotype, but it seems like the younger the driver, and the fewer the cyclinders, the more hp a CIA seems to make - lol
 
I do not believe any claims w/o a dyno unless someone is using the same configuration that has been dyno proven and is posted. As car guys, we work hard for our money and when people post silly claims, less suspecting people believe it and then spend their hard, earned money expecting something that will never happen.
 
BTW, there is a lot of evidence that adding octane booster to 87 octane fuel works a tiny bit, but does nothing, in fact, lowers hp output when added to slightly higher grades of fuel. I have seen a few tests that concluded this.

As long as it is the correect tune for the truck, you should be fine. Is it under warranty still?

A chip will probably have minor impact on your '01 Chevy 1500 HD. --Unless it has a turbo diesel, I'll certainly admit to not knowing much about your truck. If you are towing very frequently, I'd look at changing the rear end gears. That will make a much bigger difference than a chip. Or you can get a different truck that is just plain better at towing-- trucks are real cheap now, although that means your current truck is low value, too.
 
Chips have modest gains, at best, and as previous posters have said there are alternatives now as many cars support various types of reprogamming of the stock computer (ECU).
 
Turbocharged cars generally respond the best to chips and/or ECU reprogramming but this generally voids the warranty and can be risky. It can also be easy, reliable horsepower.
