To be honest you always have people arguing about which tune is better. It happened on this forum how another car was running faster then any LET tuned car. That being said I think people should remember that yea you want a fast tune but not at the sake of doing damage. A couple of guys are running a 100 octane tune so you start to get into apples vs. oranges. Yea I want a fast tune but at 93 octane because that is all that is available to me. This was the same type of war that went on over at the Diesel forum when EFI live came out for the Duramax. It was my tune vs your tune and several guys ended up with broken and melted pistons. My point is this, anyone can make your car faster but I would rather deal with a company like LET that has your engine safety in mind. I personally would rather run .1 slower and get 100,000 miles from my engine then have it shot at 30,000 from it running on the edge. I think LET always tunes a hair on the safe side and I am okay with that.
