Base Boxster performance progression

My 2001 base Boxster performs well at DE events at Sebring but it's time for some more power. Safety first so I have upgraded with Porsche sports wheels, drilled discs, OMP seats, Schroth harnesses and Brey-Krause roll bar. I know I am not going to keep the Corvettes and 911s on the straights (maybe in my Ferrari 430 but I am not going to subject that to Sebring's bumps!), but some performance gain would be appreciated. What is a good path to more power?
Intake snorkel - most people say it is not worth the minor gain
Sports muffler - lots of complaints in the forum about droning at 3000 rpm, and this is a road car too so that won't work. Any good suggestions?
Re flash the ECU - which one is a good option?
Increased mass flow rate sensor - which one?
Any other good thoughts?

Thanks for any constructive replies!

Garage
Danks sport muffler is about 15 lbs lighter & zero drone.
Secondary cat delete pipes about 15 lbs lighter, & 3 HP gain. Exhaust louder no drone.
Underdrive crank pulley 5HP & slows power steering pump speed increasing reliability.
Maybe the best thing you can do is use Gold Foil to wrap intake components & reduce intake air temps.

Thanks for the suggestions. I have heard good things about the Dansk mufflers before, so I will check out some pricing on these.

I'm confused. I thought DE stood for Driver Education. Is it also a competition? Is it important to keep up with the Corvettes and 911s on the straights ?

No of course not, you are quite right, DE is not a competitive event, except with oneself to get better. So what's wrong in looking for some more power?
