i just bought a 2002 chevy 2500hd 6.0 with 60000 miles on it. im considering a performance chip, but there are so many on the market im not sure which one would be the best. of course i would like the extra horses but i dont want to go over board with it... and of course a little better mpg wouldnt be bad either. so can anyone tell me which chip would be best or should i consider other options?
