it might just be that your lpr is a tad low and not providing enough pressure to keep up at higher speeds, no need to go taking apart everything
try raising the lpr a little first, and double check your settings to make sure you dont have some crazy short c-off setting. (i think thats the one it is, been a while since ive messed with one)
or just set it to factory fast, that usually rules out any settings issue, then go from there.
the eclipse/belsales rams are pretty nice, so are the ans mini rams. but if i was going to spend enough for an eclipse lpr id just buy an AKA one instead. better performing and i think they look nicer.
