Hey everyone! I finally got the cobra in for a dyno tune on Friday afternoon.
The car has been cutting out, popping, and just not running well in general. Replaced the plugs and coil packs the previous Friday and still didn't help.
We get her on the dyno and try a base pull to see where it's at on the current tune. Punch it in fourth and immediately let out of it due to how bad it's leaning out. Fuel load was jumping to 16/17.
We dial to a new tune slot and start fresh. Get the fuel load close and lay down 3 runs in the 530/420 range. A little more tweaking and it laid down two runs right at 560/460 at 19 degrees of timing on 93 pump gas.
I'm very happy with the results, and the car is running great. The horsepower is right at what the car put down in 2006 when the motor was brand new, and the torque is actually up from 450.
Link below is the final pull (561/464). I will attach a copy of that graph when I get home (attached below). Nice because it has the layover of the first leaned out pull for comparison.
