You need to call Ed Wright and send him the graph.

Update! I swapped in some tr7's and dropped the gap to .025" and went out and ran it up to redline in third and it felt seamless looks like its time to head back to the dyno and see what happens.

Update: Just got home from the dyno. I messed with the tune a little bit and I was able to pick up 100 more hp. The bad news is its still running out of fuel and the fueling tables are maxed. I have reached the limits of the stock pcm it seems.
This is on 91 octane.

You def need a stand alone ECU. How much boost are running?
