Should fit a Liberty 5 speed to it :D Just don't back off whilst your in gear, or else it drops out of gear! The pcm has a number of RPM limits, and limiting techniques. The factory limits have the throttle rpm limit set to 6000rpm, so as its approching 6000rpm, it starts closing. Most tuners disable this by setting it to say 7000rpm. Then there's also cylinder drop, which depending on model is anywhere from 6150 to 6300rpm. When this limit is exceeded, it drops cylinders. This is also known as hard cut. By strategically adjusting the Throttle limit, as well as the Hard limit, they can be setup so on a manual vehicle, you can keep the throttle mashed, even whilst changing gear, and the engine RPM will not buzz out of control whilst the clutch is depressed. Its something I found without knowingly doing it.. One of the car's I tuned come back to me, and said "watch this vre, full flat shift" (yes, he was greek) d.
