Oz Stang on the Dyno

Is that a canned Predator tune, or custom tune? While your numbers are low, every dyno is different. I've said it many times, that the only way to truly test it is to have a baseline on the same dyno. Either way, that does seem awfully low. If you don't have a custom tune, get one. If you do, send the chart to your tuner. Your AFR is running a little rich. Your tire pressure should really be about 40 and the run should be done in 4th gear. Some dynos don't read much difference in an auto, but some do. Honestly, those aren't the best kind of dynos for seeing horsepower. They're great for fixing problems in a tune, but their numbers can be fudged easily. Was the guy trying to sell you a tune? A Mustang Dyno, DynoJet, or DYNOmite would probably yield better, more accurate results.
