I have an auto p13 running my auto h22. The vtec was kicking in at 5500 rpms and shifting at 6000 rpms so something had to be done. I bought a chip from Advance Timing, which said the vtec would kick in at 5000 rpms and shift at 7500 rpms. I had my chip installed and the check engine light stays on and won't rev past 4000 rpms. What can I do? My old chip is still intact but cannot be put back in. It was cut out.
