Im thinking of buying a hypertech power programmer 3 for my 2004 impala ls

Question

i have a few questions about it, is it worth the $$, how much will it improve performance, and can i mess up my car if i do not program it correctly, and will it void any warranties?

Answer 1

Question 1. Yes it is worth the money especially if you drive a lot.

Question 2. I have seen these on many of my customer’s trucks and suv's and the mileage and horsepower will vary.

Question 3. Yes, with the added horsepower you can break engine and trans mounts, break the drive axle’s and blow out joints.

Question 4. Yes and No....if a problem arises the dealer will have to prove that it was caused by this, remember that you are protected by the " Magnuson-Moss Warranty Act...
