My point was that each dyno is different. Indeed over the course of 5 days the same dyno may be different. But, if you have one dyno that reads 200hp, and you tune to 230, and another that reads 300 and you can tune to 350, it doesnt matter. You made progress. The way to know for sure, without the usual dyno magic, is to find out how much the car weighs, and how fast it accelerates to for 1/4 mile. Then you KNOW. Rather than believing the dyno sheet as gospel. I'm not trying to be an Ahole...lol. I'm trying to save your emotions. Most peolpe think the car should make more power than a dyno shows. Sometimes it's just the dyno...
So for my guess, somewhere around 300-320hp at the tire. A little less I wouldnt worry about. A ton more I would want to see track times for it.
