We need to get some 1/4 mile times to compare aftermarket mods. In my opinion this will be far better than dyno results. This is the real world and what all of us will be feeling when we drive our cars. The dyno results posted on this board are all over the place, even on stock cars. It's way to easy to manipulate the dyno to show gains. Many people don't even know how to use a dyno correctly to get accurate real world readings. Especially to show gains with ECU flashes. If you're not using the dyno correctly and go to tune the ECU you are doing nothing more than correcting your dyno mistakes. Here's a couple interesting reads on dynos
