No such thing.

The only chip for the 3.7 Liberty is made by JET chips's,stage 1 and stage 2.I have the stage 2 and it did increase performance and ****** shifting but no economy gains at all.The stage 1 chip is worthless,you will actually loss power with it.

Did the stage 2 actually work? I heard the stock computer eventually learns to get around it? Did you have to use premium fuel for it? Sorry for so many questions, but you're the first person I've run across who actually used it.

It made a diiference,my butt dyno felt a gain.The biggest thing was how it improved the ****** shifting.The PCM did not phase it out since I have taken it off before and felt a mojor power loss until I put the chip back in.And yes I use premium fuel,my KJ pings(knocks) with anything less then 90 octane,has from day one and mile 3.

i am seriously thinking of getting the stage 2 chip. by improved shifting exactly what do you mean? does it get rid of that annoying automatic ****** shift? that slow engagement
