Dynoed my Si today at ProStreet!
I believe my car did pretty good!
Mods: Intake, Header, 2.5" piping, & Hondata Reflash
The lowest hp run was because the sensor at the exhuast tip fell off.

thats good! just a while back B series guys would kill to hit numbers like that....now it's so easy
and yes HP starts to drop off once everything becomes heat soaked.

thats what i did...i got a baseline of my car.
but good runs...dont know how you would know if your car had any gains or what not..but im pretty sure you did. your a/f is weird too.

I didn't dyno my car stock..but I'm pretty impressed with my numbers....according to other's that have the same mods..they are getting 190s-197 hp...so if mines pulled 199 wooot i must be pretty lucky.
I thought the car would compensate for the mods and adjust the A/F ratio? I thought I read somewhere a car runs best at a 14:1 a/f ratio, so does that mean your car is under-performing compared to what it could do?

you want to be in the 14's for normal driving.
under load you want to be as close to 13.0 as possible. 14 underload is super lean.
that is a generalization...it varies between setups

14:1 air fuel ratio is for emessions purposes only...but performance wise you might wanna consider a 12:5 -
12:7 air fuel ratio or atleast close to 13's

What do you mean by "stock exhaust" with custom 2.5 pipping?

Blah. blah , blah.. just goes to prove that we are very close in numbers with almost the same setup. He also has the reflash
And I have seen plenty of dynoes that have expensive catback exhaust and header that you would think would hit WAY higher numbers and dont.
