Similar to JDM DC2R, I was getting around a 10-15kw jump as soon as vtec kicked in, matched with a LOUD crossover....

After a tune crossover is a bit quieter (maybe even a little higher pitched...) and there is no "feeling fast" it actually is fast now and keeps building strongly

CAI is an awesome mod though, but keep in mind that afterwards you will probably feel like headers and exhaust and tune and...........
