Is your accord a manual or automatic. Also, is it an EX, LX, SE or V6?
I have a 00 EX manual and I've hit 150 but it took a while to do so.
The V6 has a better/quicker chance of doing that because of the power. The 4cyl auto is basically drag limited. With a manual, it's possible, but takes time. So make sure you have a lot of road.
BUT, as previously stated, there's no need to raise/remove the limiter IF you have one. How often do you drive 150mph.
