Default DynoJet numbers vs high altitude could be low???

Hi guys, I live in Guatemala located at 5200ft above the sea level, a few days ago I decided to have a baseline dyno chart of my totally stock ITR (only with no-cat and free flow exhaust) and the result was 154whp/111lbs.ft the dynojet it's a 224x model, the owner of the shop is not sure if the dynojet numbers are being auto-corrected, I was looking at the software but I never saw anything saying "SAE Corrected" or something....another friend dynoed his 2.0l ITR at 2500ft in El Salvador and he was pulling 212whp/143lbs.ft there w/DC sports 4-1 Header, then he also dynoed in Guatemala using a Rage Header and after 10 or more passes w/some AFR & ignition tuning the best he did was 210whp/140lbs.ft.....unfortunately there is no way to test it back w/the DC Sports header because the Rage Header is like 1/2ft longer in the collector side and some modifications were done to fit it....what do you think?

Post the graph.

Look at the bottom where it lists the run number and conditions. At the end of the line it will give CF=*.**

5200' elevation is about 15-18% difference to sea level depending on temp and humidity.

If you're duno says "actual HP" then you need to add approximately 15% or ~177whp. If not then you got some problems and you should post the graph with an A/F plot.
