08 fn2 with K&N drop in filter+Samco tb-to-airbox hose

[pboy]

hi,

I have a 2008 fn2, with just the K&N drop in filter and the samco hose that goes from the throttle body to the airbox... looks a bit thicker than the stock one, but i'm not really sure..
nothing else...everything else stock.
got the flashpro the other day and loaded the group N calibration that comes with the software, and it was a MAJOR disappointment..
The thing is I am in jhb south africa, at an altitude of 5700ft or 1.7kms above sealevel, so we are oxygen starved up here!

what calibration should I use?

There is a dealer here who does a custom "e-tune".. but i dont want to pay for the tuninig just yet: will be doing more mods during the month so i plan to do it onetime later.

please help.
