One thing about a dynojet to eliminate the feared correction (SAE) is to use the STD correction factory instead and set smoothing to 3. I know some people feel thats much more accurate.
Not a Boxster but that correction/smoothing is what more people tend to trust.

As for the smoothing factor, actually the higher the smoothing factor the more accurate the readings will be. The higher smoothing factor will limit the peaks which are usually incorrect spikes in the dyno graph.
Either way, the dyno is just a tool to use to know whether I improved or not, all dyno's will vary some depending on dyno conditions.

True I forgot NASA likes SAE correction, but they do allow smoothing set to which ever. 5 looks better but hides stuff IMO. I'm planning to get my bone stock 02S dyno'd soon but I don't know if that will be a good "before" for you or not.

NASA GTS wants a smoothing factor of 4, I'm not sure what the others (NASA ST) require.
It would be interesting to see your bone stock Box S, please post it on here when you get a chance to get it done.
I will guess it's around 220-225 RWHP, but that is just a WAG.

Ok, looks like I am now over 270 RWHP, and that is while turning a big 295 wheel/tire combo. Still making power out of a little old 3.2 liter Boxster motor. I wonder what I could do with some cams, head work, and a little more displacement ???
Has anyone tried more displacement out of the 3.2 liter block/cases ???

I did 2 pulls on my '06 3.2L Boxster S with a DynoJet last year and got 287 crank and 245 @ the wheel.
That was with a FVD Exhaust and GMS Headers w/ 200 Cell Racing Cats.
Since then I've upgraded to catless racing headers, 911 throttle body, 911 Plenum, and tune by ECU Tuning Group.
I'll be putting it on the DynoJet again in February 2015 to check my gains.
What do y'all think about those numbers so far?
