Hello folks, I have a 2013 civic si, mods are as follows, Skunk2 CAI, tsudo 2.75 inch ... downpipe, yonaka 3 inch catback (yes i need a 3 inch downpipe, I know), with Hondata. I have snagged a e-tune from the forums here, it seems to be working well, I will get a datalog and upload it, but does elevation make a huge difference that is the question?

Yea it makes a difference. I completed a tune not too long ago where I had to adjust when the car switched into open loop. The vacuum reading was different at WOT.
