I looked at the computer screen on the Dyno and it said 336hp, 1200tq. Torque was spiking cause it messed up. Horse Power was calculated with speed, I had to give them the Gear Ratio.

You pay before you go on the Dyno. I got into it with the guys there, trust me.. It's not done yet, I am calling the owner. A few of my friends and other people have had problems there also..
I can't really post that they are ******** and they mess your stuff up, but I can advise that you might have some problems there.

I understand they screwed things up. Just looking for the modification list.

I have a dyno sheet somewhere from my old setup that says 290hp 509tq, been there done that on botched dyno runs.

The 290hp number was fairly accurate actually, the TQ was gear and converter spike..
