This is with the LS1 hotcam and stock tune. The dyno was not under the best conditions but the same before and after(except 1.5hr cool down for without, 10 minute with, both after 45 min drive). Both were inside, no fan in front of car, cooling fans on at operating temp . I did add spark plugs with the cam but old plugs were fine. Also added hardend pushrods.

Without cam : 305.6hp 323tq sae corrected
With hotcam : 328.1hp 328tq sae corrected

With my current setup it looks almost like it could have a LS6 cam on the dyno sheet. But the idle doesn't .

I didn't drill the TB or mess with the stop screw either. Only drivability problems are surging a few secomds after hot start and if you rev the motor at idle(not the best for stop and go). I'll get a dyno tune after I install some LT's but stock tune will due until then.

Your times prove your putting out more power then that dyno says

 

youre 12 bolt is eating some power and itll wake up after you add LTs and get tuned.
