I saw on their website that they have a stage 1 and stage 2 tune. Of course stage 2 offered a little more power and it said something about an aftermarket exhaust. Do you think the aftermarket parts would be necessary?
Injen Intake
I was thinking the same. If you are going to spend that much money, buy the hardware yourself so that you have control of the tune and don't have to ship them your ECU anytime you need to change or update something.
Intakes and exhaust provides marginal performance gains.Major power gains are on a downpipe and intercooler.
Would the downpipe alone give a big boost in performance or must it be followed up with a tune?
It will, I ran it for about 5,000 miles without issues but i was using a defouler on the second O2 sensor. Some users have reported check engine light due to their defouler not doing its work on different downpipe brands. I used P2R = USR catless downpipe with their defouler and the smallest insert.
thought that was about the same for hondata and ktuner
The price seems a bit out of whack yeah I agree, but I think theres a caveat. This looks simple bench flashing where they are directly overwriting the rom from the video. It doesnt look like they are physically modifying the ECU or unlocking it which should make it virtually undetectable by Honda. He can probably blow out the bottom ends, ship the ECU to be reflashed to stock and Honda would never know. If this is true, it would be a nice option for those who wants to keep their warranty or does not plan to keep the car long term.
