Initial dyno on conservative tune I made 515WHP/475TQ before I did long tube headers and off-road pipes (cat deletes). Never did after so I dunno.
I say conservative because I had completely stock heads and with 3.8" stroke and over bore (resulting in 302 ci) I had a compression ratio of 10.5:1 and the tuner felt with 93 octane it was easy to cause knock/detonation.
