13,000 mile Cobra and one of the cleanest I have seen. The customer just wanted a little more and nothing crazy. Below is one of the reasons why we spend so much time on the dyno testing and spending mad time tuning. This is the same car, back to back pulls, with lab grade wideband sensors. As you can see the pulls show a shift in fueling richer on the second pull. This was with the EDDY brake ON so the power numbers are a bit higher and normal. Car made 470-491 Inertia SAE.
There are shops that have been known to "sell a tune" on a already tuned vehicle by saying they aren't safe (too lean etc.) Its not always the case. Using the load cell for fuel/air model calibration is crucial to get them correct. We use Inertia Mode for our power numbers and EDDY brake for any fueling and spark work.
The dual WBO2's were post cat (aftermarket cats) and show a .5 avg leaner reading compared to Kevin's located pre cat @ the collector which was also installed during the tuning process.
Enjoy..
