Disappointing dyno results

Horsepower is just a number, - in most cases just a conversation piece. The car will likely drive wonderfully, the only time you may miss h/p is when wide open throttle or showing timeslips, - seriously.
Make up BS horsepower, like most others. lol
Just drive and enjoy it, - make changes at your leisure.
I have always found, "if I could do it again, I'd change this".
You are there . lol
Good luck .
