I posted this on ls1tech but didnt get any replys, has anyone ever seen this, the motor runs strong, turbo works great at 5psi, but looking at the chart something goes crazy ....AFR was steady at 10.9 and timing was locked at 17.

 

Hows the car feel? Its not just something with their dyno is it?

 

car is alot faster, even with higher gears (3.42 vs 3.73) it pulls faster than when I had the nitrous on it last year. Made 2 runs and both were identical, at the same rpm both times it flatlined.
