$995 is just to put krpo on your stock ecu. ideally you want the basics, i/h/e before getting krpo just so when they put krpo on your ecu they can tune it to your mods and get the most power from your engine.

tuning ranges in price depending on the place, ive seen from $150-$250. best thing to do is to call around in your area.

and no problem about the noob questions, just happy to help.
