trust me you can kill an accord! at the most you probably lost about 2hp on the low end, but once you get up in the rpm's it will make up for it. your 0-60 times might be off. my car is still getting body work done right now, so I havent had a chance to get over and do some more work on the engine, lots of papers due, and finals. I think I just have to replace the CAS ( I HOPE ) so I will change my SN when I know 100% that my car is fixed. dont want to count my chickens before they hatch!
