I tuned it via EFI live.

Guys, this isn't supposed to be a pissing match. I'm just telling you what it made, on that day, on that dyno.

I knew that, but whats that say for the dyno it made way more horsepower on? I figured it could be the same thing with the car in dyno... Either way great numbers...
