There is a similar thread in the Engine/Exhaust/Transmission/Tuning section but since this is specific to the Si I thought a post here may be helpful in the future. The thread I referenced can be found here:
http://www.civicx.com/threads/ktuner-vit-legends.16648/
and another: http://www.civicx.com/threads/vittuned-stage-1-offer-for-the-civic-si.15128/
I like most have done a lot of reading and planning on what mods I want to do for performance. I debated a tune for a short time due to warranty concerns, but ultimately decided to make the purchase and let what happens happen. I bought the Si to have fun, and trust the reliability of Vittuners and the Ktuner product.
My Civic Coupe Si is completely stock as far as the drive-train is concerned. I have ordered the PRL intake but that is still a little ways off. I have used only 93 octane since the first dealer fill was emptied.
I watched all the Ktuner tutorial videos on Ktuners site and they were helpful:

There are no instructions other than what you will see online. see here http://ktuner.com/downloads/
The only problem I had was finding my ECU Software ID for my car on the Ktuner screen that Vit requires before sending the tune via email, but after using the Ktuner help search box I was able to locate it. Vit has prepared a 19/25 (Sport Buton) dual tune specifically for the Si, titled Stage 1 tune. https://vittuned.com/ktuner-flash-civic-si-combo-stage-1.html
Before installing the tune I had ideas of a PRL front/downpipe combo and their FMIC kit in progress. After taking the Si out and pushing the SPORT button and activating the 25psi tune I am content, very content. I will still be adding the PRL intake but that is probably the most I will do. Certainly a clutch would be needed for anything more, maybe even for the 25 psi tune as it is.
My suggestion is this, before adding all those bolt ons try the 19/25 Stage 1 from VIT, if you need more then go from there. Chances are the transformation will be enough just from the tune. The fun factor just went to a 10. AMAZING!
