I pretty much have a stock Trans Am with a WS6 hood, air box, and a 180 thermostat. I was wondering what kind of gains I could possibly see if I had it tuned on a chasis dyno. The package I would buy would consist of 90 percent on dyno, and 10 percent street conditions.

 

Aside from requesting things like fan on/off temps, trans. settings, or speedometer recalibration, the only things he would need to do is dial in your WOT AFR and maybe up your WOT spark table a bit (assuming you don't have trims dumping in excess fuel). Ideally, you want that done on the street since those are the conditions the car will see. I'm in the same boat with a stock setup from the MAF to the cats and hoping for 15 or so more hp. We'll see how the car has progressed at the track tomorrow and if I learned anything at all in the past month.

 

So we're talking gaining maybe 15 rwhp? Anyone in the DFW area that does this - that's good AND has some integrity?
