What does this dyno graph say about the tune?
Looking at buying this car but I'm concerned about the street tune it has.
Motor is healthy and was compression tested by speed inc . It is a si5 cam, bolt on ls6 with ls1 heads.

Looks like it just lost spark plug input from thier sensor on the dyno.
on another note, The dip from 3200 t o 4200 making you lose 26ft of torque could be wheel spin, missing timing, to much timing and getting kr,or a dirty air filter.
The spikes/ missing sections on the run are from the spark signal being lost. If it wasnt the actual sensor, then it was possible that it was a missfire on that cly, However, that would be more rare than just it being the sensor being wrong.
I would also Richen up the cal a bit too. Shouldnt hurt power any, but will be a bit more safe.
