Put the 5.0 down on the rollers yesterday. Averaged 389 rwhp/372 rwtq SAE on a dynojet. Car is stock except for a Roush axleback.
Not to shabby for a basically stock naturally aspirated 5 liter.
Got a SCT X-Cal 3 (w/BBR tune) and JLT CAI on the way from Stage 3. Should easily go above 400 rwhp with just a CAI/TUNE!
Ran a 12.75@108 last weekend, too (stock on DR's). Should dip in the way low 12's at the very least on the CAI/TUNE.
