My '03 Cobra charts.

First was baseline run, bone stock except Steeda catback. This was with the paper filter removed.

Then, I installed a JLT True Cold Air, Billetflow 2.76 upper pulley/idlers and a custom tune with an SCT Xcalibrater 3 from Amazon Tuning Solutions. Here's the chart and comparison. A/F was a bit rich in the high 10 average. We leaned it out to about an 11.5 average. These numbers are uncorrected. The temp was about 60 degrees with a cool breeze. Corrected was only adding about 1-2 hp. Temp was perfect.

Bottom is a comparison chart....

Night and day difference. It actually will break loose all the way through third now which it couldn't do before. It definately woke her up. :coolman:
