I have a non-vtec skunk2 chip for my ls 95 ls integra, when I bought it they charged me for two and sent me two of them, and I noticed some gains on the highend part of my pwerband, The chip has a high redline of 8500 which is ******* crazy. I never took it up that high. If you have intake you will notice a much louder noise from new air curves. I will sell it cheap for 25 bucks with shipping I Paid $60.00 for it and 120 for both.
