I would like to get everyone's opinion on the power chips. Anyone tried one and actually liked it? Project M-P-G said that the Hypertech Chip made a good difference, especially for towing. Is one brand better than the others? Thanks.

 

Also, do all power chips require the use of Premium fuel? I was hoping for better power, but it would have to make a pretty substantial difference for it to be worth putting 92 octane in every week.

 

I have a HyperTech chip in mine and noticed a difference when I did it but had to run 92 octane or it would ping regardless of where the timing was set. I ended up removing it because I was troubleshooting another related problems and have nver reinstalled it. I mainly noticed the gain when towing my boat and at interstate speeds.
