I have a 2000 Chevrolet Silverado with the 5.3L V8 and I was considering buying a reprogamer for the computer for more power. Are these harmfull to the engine? Are they worth it? All opinions are appreciated.

The engines are just about Maxed out now if you want more power get a bigger engine . when you start changing the compuiter you are asking for trouble my brother-n-law did and last week I had to go get his truck and this week $2500 later he is driving it with a new engine . 2002 5.2 LTR .

Most of the gains come from advancing the timing and richening up the injectors. You can do the same thing yourself for about a buck. Find the air inlet temperature sensor and add resistance to trick the computer into thinking it is 25 degrees colder outside. The computer will automajicaly richen your fuel and advance your timing and you get more power. Not sure exacally how the chevy is set up but they all work the same way. On the last one I did (2005 Ford Escape) my company car I took the sensor off and read the resistance. I put it in the refrigerator and read the resistance again. I installed a radio shack potetiometer in series and set it for the total resistance I got when it was in the fridge. It wakes the engine up and gives it crisp throttle response. The programers change shift points, tourqe converter lock-up and rev limits but cost you. A 160 degree thermostat works in the same way on the computer so if you do both you will see the same gains as the chip reprogramer.

Nope..... .... The re-programming leans the wide open throttle mixture. The factory sets the mix very rich so the engine detonates less when cheap crap gasoline is used. And the cat convertor runs much cooler when over rich compared to slightly rich. The spark maps are advanced a bit and the sensitivity of the knock sensor reduced some. The torque limiter is shut off. The transmission line pressure will be steped up a few psi. The w.o.t. shift points will likely be raised. The dash fuel economy meter inputs will be re-worked to give the impression of improved mileage.

I do not remember if I read this somewhere or saw it on TV but think it's possible to do some damage to your engine if your careless. Increasing HP my result in to high of an RPM. Out of warranty of you still had one.
