Its all in the tuning, maybe the setup just favors the spray. Has it ever been on the dyno before (anything to compare to) or was this the first time? Usually if a dyno is off its off across the board. In other words your runs would be consistent with one another but not accurate to what the car is truly doing. Rarely do they turn out erratic numbers from one run to the next. So, your 2 numbers may be off, but they are off proportionally to one another. Obviously I wasn't there when you ran your car, just letting you know what I've learned.

Did you degree the cam? If not, it could almost be a tooth off. I remember back in the TL1 days, a guy put a GM847 cam in his and ran 101 in the 1/4. He was pissed, took it apart and found it was a tooth off - corrected it and went 115, so sometimes its not noticeable - he even said the idle wasn't very different before and after.
Since you seem to have a decent tuner, I'd check the mechanical items first.

What i dont get is lets say you do make 450whp, why did you only gain 95whp with 150shot?? So either your na numbers are lower then 450 or your spray tune isnt righ...
If it was my car i would bring it to a diff well known tuner and have him look at it, better to be safe then sorry
