So i know alot of people have info, but ive searched and havent came across anyone with the stage 1(from what i hear around 10-15hp gain). I know with the stage 1 you will be able to skip from buying the valve train upgrade. Also ive read that alot of people have a hard time with idle and all that other stuff because they dont have the best tuning system out there, Kpro. But i dont have a grand for that so what would be neccessary for a stage 1 cam? ie. cam gear or some sort of tuning system that doesnt break my bank

If you have any plans at all for the car, K-pro is a much better investment. I mean a cam is over a third the cost of k-pro. Just save your money get a standalone, and pick up a stage 2 cam and valve train later on. Check out ephatch.com and clubrsx.com k-pro comes up on there not too infrequently used.

Stage 1 is drop in replacement. Don't need to tune it. The stock tune is already rich so you'd def see some gains with a higher lift cam. You have idle issues with stage 2 and above.

its more like a 5whp gain with stage 1, maybe 10 with cam tuning.
