I'm sure your car is running just fine as long as the A/F is within nominal.
I've seen a lot of stock revups tested on the same dyno machine. (IE Dynapack at Church auto) and they are all within +/- 2HP. Assuming the ECU isn't in lazy mode, the repeatability is so good from engine to engine I seriously doubt there is any kind of weak engine issue.
$10 says your ECU was in lazy mode or it was simply the dyno you ran it on.
You could probably go back to that same machine tomorrow and see another 10+HP. It just happens from time to time.

I never have done the ecu reset during any of my mods. I always disconnect the battery and then reconnect it when im done. Does this work the same way or do I have to do that whole long list of things ha? Thanks.

+1. Doesn't do a thing for power gain, just delivery. Effectivey, you're shortening your gears and rowing quicker. That's it... If you're planning on staying NA then go for it, otherwise it's kind of a waste.

Oh I know the 3.9 isnt going to add any power wise, Im getting it because its going to accel quicker through the gears. All in all It seems like 300whp is going to be a waste of a goal to get to N/A. Pricing is going to be too much for what I have in mind. Question though, If I do the 3.9 final drive, will that have negative affect on a vortech s/c like it would on a turbo car?

Final Drive on the dyno WILL read the same. This is because the dyno operator will input the new final drive and after that it will adjust for the HP. So if you gain or loose hp on the dyno with the FD something else changed.

My bad, I thought they all did.
