Default Dyno results

As I stated before, here are the results. 390 rwhp, 363 torque. Mods are listed in sig. I was hoping for the 405-420 range, I am still not disappointed with the 390. I am running a rich 11.2 A/F ratio. Would like to hit the 4-405 range with some tuning and tweacking. Now time for the strip!

11.2...I'm no expert, but that would seem way too rich. And, from what I'm told, your cats won't last to long like that. Not to mention, you will pick up a whole lot more hp if tuned to between 12.8-13.2 A/F.

Congrats and have it tuned so you can get over that 400hp hump!

W/O tuning you are leaving 10 to 15 HP on the table.

Hey thanks, rich it is. I am already running the off road pipes, hi-flow cats are sitting on the bench. A little more tuning, I will hit the 400 plus zone. Hang on!!

Mine was 11.5:1 from the factory...Rich, but not rich enough to hurt the cats. Lean conditions are what hurt the cats, cat overtemp dumps fuel to protect the cats.
