Don't get overly wrapped up in dyno numbers at this point. Keep in mind that the only thing a dyno number means is that at the time it was taken with the engine fitted with certain components on this particular dyno and the weather outside being such and so you have this number as a base line.
Dyno results will vary quite a bit depending on what's on the engine. Water pump? Probably good for about 15 HP. Street mufflers? Probably good for about 40 HP. No air filter? Probably good for about 20 to 30 HP. This particular dyno calibration compared to someone elses dyno? Variations of probably up to 10%.
For the experts reading this I said PROBABLY. Your result may vary.
The point I'm trying to make is that a dyno number shouldn't be seriously looked at as anything more than a reference point to see how whatever changes you've made effect the efficiency of the engine providing subsequent runs are made on the same dyno.
As previously stated, run the car, have fun with it, think or dream about what you'd do to change it (my dreams are filled with IR EFI from Very Cool Parts which I may or may not get to this winter), change your mind about what you want to do to it and then, after a few thousand miles of driving, reconsider it all again. It gives you something to do on the long straightaways between stop lights or corners.
The idea is to enjoy the car and not take it too seriously.
